A 110. g sample of copper (specific heat capacity= 0.20 J/g C) is heated to 82.4 C and then placed in a container of water at 22.3 C. The final temperature of the water and copper is 24.9 C. What is the mass of the water in the container, assuming that all the heat lost by the copper is gained by the water?
How much heat is required to warm to 0 degrees C and then melt a 100ml block of ice( at 20 degrees C) that is 100ml in volume? Density of ice is 0.92 g/ml. DeltaHfus=6.01 kJ/mol. DeltaHvap=44kj/mol. Heat capacity of ice= 2.09 j/g C. Heat capacity of water= 4.184 J/g C.
