Heat is a form of energy that is transferred between systems or objects due to a temperature difference. It flows from hotter to cooler objects until the two reach thermal equilibrium and have the same temperature. Heat can be measured in units of joules, calories, or BTUs.
Here are some MCQs on HEAT
1. The transfer of thermal energy between two objects in contact is called:
A) Convection
B) Radiation
C) Conduction
D) Insulation
2. Which of the following materials is a good conductor of heat?
A) Wood
B) Plastic
C) Glass
D) Copper
3. Which of the following is NOT a unit of heat?

4. Which of the following is an example of radiation?
A) Touching a hot stove
B) Heating a pot on a stove
C) Feeling the warmth of the sun
D) Wearing warm clothing on a cold day
5. The amount of heat required to raise the temperature of 1 gram of a substance by 1 degree Celsius is called:
A) Specific heat
B) Heat capacity
C) Thermal conductivity
D) Convection coefficient
