These are Heat engine questions:
1. what do you expect to happen to the pressure and volume of the closed system of air that has a 200g mass on top of it when you heat up the air inside the system? explain you're reasoning.
2. what do you expect to happen to the pressure and volume of the closed system of air that is still heated as you remove the 200g Masson top of the piston? Explain you're reasoning.
3. do you expect a closed system air to return to the original pressure and volume when the heat is removed? explain your reasoning.
1. As PV = nRT
If you increase the T, then P and/or V bound to increase. As 200g mss is put top on the top of piston it will resist the change in volume, so pressure increase at first.
2. As they is no boundation, the volume of system will increase till internal and external pressure become equal.
3. No, That depends on the type of process either its adiabatic, isobaric or isochoric.
