2. WHAT IS HEAT ?
● Heat is the form of energy that is transferred between systems or objects with different
temperatures (flowing from the high-temperature system to the low-temperature system).
Also referred to as heat energy or thermal energy. Heat is typically measured in Btu, calories or
joules.
3. WHAT IS TEMPERATURE ?
● Temperature, measure of hotness or coldness expressed in terms of any of several arbitrary
scales and indicating the direction in which heat energy will spontaneously flow—i.e., from a
hotter body (one at a higher temperature) to a colder body (one at a lower temperature).
4. HOW CAN WE MEASURE OF BODY
TEMPERATURE ?
● Your body temperature can be measured in many places on your body. The most common ones
are the mouth, the ear, the armpit, and the rectum. Temperature can also be measured on your
forehead. Thermometers show body temperature in either degrees Fahrenheit (°F) or degrees
Celsius (°C).
5. WHAT ARE DIFFERENT TYPES OF
THERMOMETER ?
CLINICAL THERMOMETER LABORATORY THERMOMETER
6. WHAT IS OUR NORMAL BODY
TEMPERATURE ?
● Normal body temperature varies by person, age, activity, and time of day. The average normal
body temperature is generally accepted as 98.6°F (37°C). Some studies have shown that the
"normal" body temperature can have a wide range, from 97°F (36.1°C) to 99°F (37.2°C).
7. SCALE TO MEASURE BODY
TEMPERATURE ?
● The instrument which measures the temperature of body is known as thermometer.
Thermometer has scale in degree Fahrenheit (℉) and in degree Celsius (℃). The Fahrenheit
scale has the melting point of ice at 32° F and the boiling point of water at 212° F.
8. CONVECTION,CONDUCTIONAND
RADIATION
● While conduction is the transfer of heat energy by direct contact, convection is the movement
of heat by actual motion of matter; radiation is the transfer of energy with the help of
electromagnetic waves.
9. WHAT IS SEA BREEZE AND LAND
BREEZE
● Land breeze: blowing breeze from land towards the sea is called a land breeze. ...
● Sea water being at higher temperature, the air becomes lighter and rises up. Air from land
being at higher pressure. So air from land starts blowing towards the sea and gives rise to a
land breeze.
