Question

Calculate the specific heat capacity of substance x from the following data. A container made of the substance x has a mass of 3.6kg and contains 14kg of water. A 1.8kg-piece of the substance x initially at the temperature of 180°C is dropped into the water. The container and the water initially have a temperature of 16.0°C and the final temperature of the system is 18.0°C.

Answer 1

the sum of heats gained is zero

3.6*cx*(18-16)+ 14*cw*(18-16)+1.8*cx*(18-180)=0

solve for cx
