principle of calorimetry

Explanation:

Answer 2

Answer:

The given principle is called as the "principle of calorimetry".

Explanation:

• The heat from one body to another body only transfer normally from a heated body to a colder surrounding and the transfer depends on the surrounding heat or temperature that exist around the body.
• For example: If hot glass is kept in room temperature then the glass will tend to transfer the heat to the surrounding, so that both of them becomes equal in temperature.
• Similarly it happens to cold glass the transfer of heat from surrounding to the colder class takes place such that the temperature of the surrounding and glass becomes same.
