Answer the following:

Which principle is used to measure the specific heat capacity of a substance?

Principle of heat capacity:

⇒ If heat is exchanged between hot and cold object, the temperature of the cold object increases (energy gain) and the temperature of the hot object decreases (energy loss).

⇒ Until the objects attain the same value, the temperature continues to change.

⇒ If the system of both the objects is isolated and close in a heat resistant box, then no energy can flow from inside the box or come into the box.

⇒ In this condition, we get the following principle:

Heat energy lost by the hot object = Heat energy gained by the cold object.
