QQuestion
(a) Atmospheric temperature after a hailstorm is greater than the temperature during the hailstorm. State True or False.
(b) Which thermal physical quantity of a frying pan changes by making its base heavier?
(c) State the principle of Calorimetry.
✓Answer
(a) False
Explanation:
After the hailstorm, ice absorbs the heat energy required for melting from the surroundings, so the temperature of the surroundings falls further.
(b) Making the base heavier increases its heat capacity because heat capacity depends on mass.
(c) The principle of calorimetry states that when a hot body is brought in contact with a cold body, heat lost by the hot body equals heat gained by the cold body, provided there is no heat loss to the environment.
