An aluminum cup of unknown mass contains 200 g of water and a 100 g copper stirrer, all at 20 degrees Celsius. A 600 g sample of silver at an initial tempreature of 100 degrees Celsius is placed in the water. The stirrer is used to mix the water until the mixture reaches thermal equilibrium at 30 degrees Celsius.

A. How much heat does the water absorb?

B. How much heat does the copper stirrer absorb?

C. How much heat does the silver give off?

D. How much heat does the aluminum absorb?

E. What is the mass of the aluminum cup?
