Determine the pressure at which mean free path of argon (g) at 25°C become comparable to the size of a 1.0 litre vessel that contains it? Assume that σ = 0.36 nm².

Calculate the pressure exerted by one mole of carbon dioxide gas in a 1.32 dm³ vessel at 48°C using the van der Waals equation. The van der Waals constants are a=3.59 dm⁶ atm mol^-2 and b=0.0427 dm³ mol^-1.

Determine the critical temperature of a van der Waals gas for which P_c is 100 atm and b is 50 cm³ mol^-1.

For hydrogen gas, calculate the root mean square velocity <c²>^1/2 at 0°C.

Determine the quantities that are held fixed in a canonical ensemble.
