A 96 g piece of ice at 0.0°C is placed in an insulated calorimeter of negligible heat capacity containing 100 g of water at 100°C.
(a) What is the final temperature of the water once thermal equilibrium is established?
(b) Find the entropy change of the universe for this process.
A 33.0 g bullet moving at 434 m/s strikes a 5.0 kg bag of flour that is on ice, at rest. The bullet passes through the bag, leaving at 295 m/s. How fast is the bag moving while the bullet exits.
