Question

A piece of metal of mass 400g of specific heat capacity 500jkgk is place in an oven to attain a study temperature and transfer in to a calorimeter with 1000g of water at 30c the thermal capacity of calorimeter and stirrer is 105jk final temperature of the mixture 35c fine the temperature of the oven

Answer 1

calorimeter and water goes up from 30 to 35

heat in
105 J/degK (35-30) + 1.00 kg * specific heat of water * (35-30)
heat out
0.400 * 500 J/ kg deg K ( T - 35)
heat in = heat out, solve for T
