a copper can of mass 0.15 kg is heated to 120 "C. 0.016 kg of ice at 0'C is then put into the can and it changes to water at 20'C.Estimate the specific heat capacity of copper
個答案係446j kg-1 'c-1 想問下點解會大過standard 387j kg-1 c-1 咁多既

I don't think it is due to heat lost to surroundings.
mc(T-T') = E released by the copper = E absorbed by the ice
c is larger because energy absorbed by the ice is larger.
Why?
Because heat is absorbed by the ice from surroundings.
