question

A piece of iron weighing 20.0 g at a temperature of 95.0°C was placed in 100.0 g of water at 25.0°C. Assuming that no heat is lost to the surroundings, what is the resulting temperature of the iron and water? Specific heats: iron = .108 cal/g\rule{1em}{1pt}C°; water = 1.0 cal/g\rule{1em}{1pt}C°.
