1. How do the specific heats of the samples compare with the specific heat of water? 

2. Discuss any unwanted heat loss or gain that might have affected your results 

3. To measure the heat capacity of an object, all you usually have to do is put it in thermal contact with another object whose heat capacity is known. Suppose that a 100 g chunk of metal is immersed in boiling water (100°C). After a time, the metal is removed and quickly transferred to a Styrofoam cup containing 250 g of water at 20°C. After a little while, the temperature of the contents of the cup is a found to be 24°C. You may assume that the heat transferred from contents of the cup to its surroundings, and the heat capacity of the cup itself are both negligible. 

a. How much heat is gained by the water in the Styrofoam cup? 

b. How much heat is lost by the metal? 

c. What is the specific heat (in Jg K) of the metal?
