Q1. A 25 g of copper pellets are removed from a 300 C oven and immediately dropped into 120 mL of water at 18 C in an insulated cup. What will the new water temperature be?

Q2. A 5.00 g lead bullet travelling at 470 m/s is stopped by the large tree. If half the kinetic energy of bullet is transformed into internal energy and remains with the bullet as the other half is transmitted to the tree, what is the increase in temperature of the bullet?
