Physics
In a laboratory experiment to measure specific heat capacity of copper, 0.05 kg of water at 60°C was poured into a copper calorimeter with a stirrer of mass 0.20 kg initially at 10°C. After stirring, the final temperature reached to 25°C.
Specific heat of water is taken as 4200 J/kg°C.
(a) What is the quantity of heat released per kg of water per 1°C fall in temperature?
(b) Calculate the heat energy released by water in the experiment in cooling from 70°C to 45°C.
(c) Assuming that the heat released by water is entirely used to raise the temperature of calorimeter from 10°C to 45°C, calculate the specific heat capacity of copper.
