1)Identify if the following processes are when Q = 0:

a. rubbing your hands together to warm up

b. boiling water slowly on a stove

c. Doing rapid bicep curls

2) imagine that an iron belt is wrapped snugly around Neptune which has a radius of 24,622,000 m. The belt is warmed so that its temperature is raised by 2 degrees Celsius. Assuming uniform linear expansion, how much will the belt be sitting above the surface of Neptune after it has expanded? The coefficient of linear expansion of iron is 12.2x10-6/ degree Celsius.

3) An ideal gas is kept in a rigid container of constant volume. The pressure inside the container is 1.5 atm with an initial temperature of 300 K. If the pressure is increased to 8 atm, what is the new temperature inside the containe?
