A copper calorimeter can with mass 0.100 kg contains 0.160 kg of water and 0.0180 kg of ice in thermal equilibrium at atmospheric pressure. if 0.750 kg of lead at 255°c is dropped into the calorimeter can, what is the final temperature? assume that no heat is lost to the surroundings. the specific heat of copper is 385 j/kg °c, specific heat capacity of water is 4182 joules/kg °c, the latent heat of fusion of ice is 33600 j/k, the specific heat capacity of lead 128 j/kg c°.
a) 34.6°C
b) 42.9°C
c) 51.3°C
d) 58.7°C
