2. Given a closed container of volume 1 L containing 50 g of helium gas, calculate the following: a. The pressure at T = 6 K, assuming that the gas is an ideal gas. b. The pressure at T = 6 K, assuming that the gas obeys van der Waal's equation of state. c. The pressure at T = 6 K, assuming that the gas obeys the virial equation of state truncated after the second term. d. The state of the fluid at T = 4.2 K. (Hint: 4.2 K is below T. and 50 kg/m³ is greater than p、 @ 4.2 K.)
