Question

A piece of copper weighing 500g gives out 1,200 calories of heat when it is cooled from 80degree to 10degree . find its specific heat capacity, thermal capacity and water equivalent​

Answer 1

Answer:

calorimeter of mass 50g and specific heat capacity 0.42Jg−1℃−1 contains some mass of water at 20oC. A metal piece of mass 20g at 100oC is dropped into the calorimeter. After stirring, the final temperature of the mixture is found to be 22oC. Find the mass of water used in the calorimeter.

[specific heat capacity of the metal piece =0.3Jg−1℃−1
