6 What is the average kinetic energy of a monotomic gas at 0 °C?
7 What is the internal energy of a monotomic gas at 0 °C?
8 Thermal energy can be transfered through conduction. Using the equation that describes how quickly energy is transfered through conduction as a hint, describe 4 things you could change about the pictured situation to increase thermal conduction.

9 If the pressure is doubled in an inflated, but closed, balloon while maintaining the same temperature, then by what ratio does the volume in the balloon change by?
10 A sealed weather balloon is launched at rises very, very, high in the atmosphere. It Helium in the balloon is 1/3 its original temperature, then how did the volume change if the pressure doubled?
