Understanding of thermal processes?

[Identity]

Can someone please help me with my physical understanding of thermal processes?

This is what I understand thus far, is it right? Also I have some questions :P
Isochoric: Lock the piston in place while heating/cooling.
Adiabatic: Push or pull out the piston very fast.
Isobaric: Slowly heat a gas and let the piston pull out. (What is the analogue for compression?)

Isothermal: ? I don't really how an isothermal process occurs physically

Thanks :)

Perform the process in a constant-temperature bath, and go slowly enough that the system is always equilibrated at this temperature.

Ah ok, thanks Mapes
