When salt is added to water, the salt crystals disappear and the water tastes salty, forming a homogenous saltwater mixture where the salt and water particles are evenly mixed on a microscopic level. In a heterogeneous mixture, the individual substances that make it up are not evenly distributed and their particles remain visible, such as a suspension where one substance is suspended in another. The document provides examples of homogenous and heterogeneous mixtures and directs the reader to activities in the textbook to further explore the differences between the two types of mixtures.
Heterogeneous and Homogeneous Mixtures are discussed in this presentation. High School chemistry, physical science, environmental science, earth systems, and material science students will benefit from this presentation. All essential introductory concepts are presented here.

A mixture forms when two or more substances are combined such that each substance retains its own chemical identity. Everywhere around us are made up of mixtures. We can see them in nature, along the surface of the earth, in the oceans and in the foods we eat. There are infinite numbers of mixtures that can be combined into homogeneous or heterogeneous.

Solution
Ans 1 . A homogeneous mixture is that in which components of mixture are present in same proportion ,that is , uniform composition through the mixture .For example , water , air , vinegar are homogeneous mixtures.
While a heterogeneous mixture is that in which components of mixture are not present in same proportion , that is , non-uniform compostion throughout the mixture . For example , sand , granite , blood are heterogeneous mixtures .
So, on the basis of this , we can determine a mixture to be homogeneous or heterogeneous by checking the composition of mixture whether it is uniform or not .

Solution
1.One substance which is dissolved in another substance.
Solvent is the one which dissolves the solute.
When both are same state form homogeneous mixture of solution with different colour from it\'s individual.
2. Solutions are composition of 2 or more substances in liquid form.
Heterogeneous solution is one which has different phases or parts dissolved in solution with different ratio. Visibly different colour or phase.
3. Here solvent is gas. Only gas solute only dissolve in this gas condition not solution(liquid form). So gas solution not possible.
4. Water is the one which has capable of dissolve variety of solute. It it polar in nature. Hydrogen has positive charge and oxygen gas negative charge for polarization.

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

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

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.
3. When a salt is added to a water, the
crystals disappear and the distilled
water tasted salty. This shows that
there are two kinds of particles in the
glass and the resulting system is a
saltwater mixture.
In this mixture, only one substance is
visible, the water, and since the water
is liquid, only the liquid phase is
recognizable.
5. This type of mixture with
uniform appearance is
called homogenous
mixture.
It is also called solution.
6. Mixtures that contain
substances that are not
evenly distributed, and the
particles have no uniform
appearance is called
heterogeneous mixture or
suspensions or coarse
mixture.
