Energy is the ability to do work.
Everything that happens in the world uses energy!
Most of the time we can’t see energy, but it is
everywhere around us!
“HEAT”
Heat is a form of energy that flows from warmer bodies to colder bodies.
It is viewed as a form of energy that is transferred from one body to another due to a difference in temperature.
The SI unit of heat is joule (J).
Common unit of heat is calorie.
CALORIE the amount of heat needed to change the temperature of one gram of water from the pressure of the atmosphere.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

How to Make a Field invisible in Odoo 17Celine George
It is possible to hide or invisible some fields in odoo. Commonly using “invisible” attribute in the field definition to invisible the fields. This slide will show how to make a field invisible in odoo 17.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
2. Heat
• Heat is a form of energy which can cause hotness
to a body.
• Heat can only be transformed to other form of
energy.
• When a body possess or gains heat energy it• When a body possess or gains heat energy it
tends to become hot.
• Example:- Water become hot when kept on a gas
stove burner. Here gas stove is the source of heat
and water is gaining this heat energy.
• But if a body looses heat it become cold

4. How does heat energy gets transformed
into other form of energy
• Example1:- In thermal power
station heat energy is
transformed into electrical
energy.
• Example 2:- In nuclear power
plant, nuclear energy gets
transformed into heat energy,
• Example 4:- In electrical bulb,
the electrical energy gets
converted into heat energy of
the filament which is then
converted into light energy.
• Example 5:- during working of
heater or geyser electricaltransformed into heat energy,
and then heat energy into
electrical energy.
• Example 3:- On rubbing palm
against each other, palms
become hot. Here mechanical
energy is converted into heat

5. Temperature
• The degree of hotness of a
body is called its temperature.
• when a object is heated it
becomes hot along with this
object will also expand.
• Cooling of object results in
contraction.
• Effects of heat:-
1. Change of state of matter:-
solid ice converts to liquid
when kept at room
temperature. When it is
heated more it converts into
vapour. But cooling cancontraction. vapour. But cooling can
reverse this process hence it
is reversible process.
2. Bring chemical change in a
substance:- Food getting
cooked when heated. Milk
forms curd when it is warm.
These changes cannot be
reversed hence they are
chemical changes.

7. Thermometer
• The device use to measure the temperature of an
object is called thermometer.
• Thermometer use scale to give the reading of the
temperature.
• Celsius:- This scale is most commonly used. Its written
as °C. Example 30°C
• In Celsius scale the freezing point of water is taken as• In Celsius scale the freezing point of water is taken as
0°C and that of boiling point of water is 100°C.
• The stem of thermometer carry marks as horizontal
lines to read particular temperature these marks are
called Calibrations.
• There are different types of thermometer clinical,
industrial, digital etc.

9. Difference between clinical and
laboratory thermometer.
Clinical thermometer
• A clinical thermometer is
shorter than laboratory
thermometer.
• Clinical thermometer is
removed from body to read
the temperature.
Laboratory thermometer
• A laboratory thermometer is
much longer than clinical
thermometer.
• Laboratory thermometer is
read while its bulb is in close
contact with the object.the temperature.
• Capillary of clinical
thermometer have a kink just
above its bulb.
• The range of clinical
thermometer is 35°C to 42°C .
• Clinical thermometer is use to
measure body temperature of
humans and animals.
contact with the object.
• Laboratory thermometer has
straight capillary.
• The range of laboratory
thermometer is 0°C to 100°C.
• Laboratory thermometer is
use to measure temperature
of chemical reactions and
laboratory processes.

10. Precautions to be taken while reading
laboratory thermometer.
• For taking the reading with clinical thermometer, the bulb
of the thermometer should be in proper contact of object
whose temperature is to be measured.
• For example:- for taking temperature of boiling water in
beaker the thermometer had to be immersed in water and
not touch side of beaker.not touch side of beaker.
• The reading of the temperature should be taken without
removing the thermometer from its position.
• The eye of the observer should be at the same vertical level
as that of the mercury in the capillary tube.
• The thermometer should not be use to measure the
temperature below its lowest marking or above its highest
markings.

11. How to use clinical thermometer?
• The thermometer must be washed preferably with
antiseptic lotion like dettol or spirit or at least with
clean water and dried with a clean cloth.
• Thermometer should be given soft 2 to 3 jerk to bring
mercury in capillary below 37°C.
• Thermometer should not hit any object while giving
jerk, otherwise the bulb will break.
• Thermometer should not hit any object while giving
jerk, otherwise the bulb will break.
• Note the mercury reading in proper light.
• Mercury is poisonous metal so make sure it does not
break in mouth while taking temperature. Or measure
temperature underarms.
• If mercury spills by accident then it can be picked up by
kneaded wheat dough by rolling it over mercury.
