Question

A 25g block of copper is placed on a 100g piece of ice:

a.) If it the copper looses 77 J as its temperature drops by 8 degrees, what is the specific heat of the copper?

b.) If the copper starts at 300K, and the ice starts at 271 K, what will be the final temperature of the water and copper? (C_ice=4.186 J/gK, L_ice=334 J/g

c.) if the copper was originally a 10 cm long rod, how much do we expect it to have shrunk due to thermal expansion? (α=17 x 10^-6 per K)
