Question

Relation between heat gained or lost by an object with is mass

Answer 1

The amount of heat gained or lost by an object when its temperature changes can be calculated by the formula, where is the heat gained or lost, is the mass of the object, is its specific heat, and is the change in temperature.

Answer 2

Answer:

The heat gained or lost by an object is directly proportional to its mass.

Explanation:

From the law of calorimetry,

Heat gained by the body=Heat lost by the body     (1)

According to the heat law,

$Q=mc\Delta T$           (2)

Where,

Q=heat lost or gained by the body

m=mass of the body

ΔT=change in temperature of the body

If "ΔT" is kept constant equation (2) can be written as,

$Q\propto m$       (3)

Hence, the heat gained or lost by an object is directly proportional to its mass.
