Pressure in canonical ensemble

[QUOTE="SchroedingersLion, post: 6025665, member: 624040"] Greetings, I am having a hard time in understanding intuitively how pressure does not automatically stay constant in a canonical ensemble (=NVT ensemble). Pressure in a closed system is the average force of particles hitting against the wall of said system. The obvious way to manipulate pressure in a closed system is to either shrink the volume so the particles would have less space and collide with the boundary more often, or to increase the temperature so the average momentum of the particles would increase and thus the force they hit the boundary with. But both V and T stay constant in the canonical ensemble. So how come pressure fluctuates? Regards SL [/QUOTE]
