A sealed piston-cylinder system contains gaseous krypton.
Explain, in terms of atoms:
the effect of heating the gas (while keeping the volume constant) on the pressure of the krypton,
the effect of expanding the volume of the cylinder (while keeping the temperature constant) on the pressure of the krypton.
