Q1. A 500.0 g pot of water at room temperature (20.0 degrees C) is placed on a stove. How much heat is required to change this water to steam at 100.0 degrees C?

Q2. A 70 kg man weighs 686 N on the Earth's surface. How far above the surface of the Earth would he have to go to "lose" 12% of his body weight?

Q3. A gymnast of mass 56.0 {rm kg} hangs from a vertical rope attached to the ceiling. You can ignore the weight of the rope and assume that the rope does not stretch. Use the value 9.81 {rm m/s^2} for the acceleration of gravity.
