Question

Liquid helium at 4.2 K has a density of 0.147 g/mL. Suppose that a 1.50-L metal bottle that contains air at 110K and 2.0 atm pressure is sealed off. If we inject 80.0 mL of liquid helium and allow the entire system to warm to room temperature (25 °C), what is the pressure inside the bottle?

Answer 1

I do not believe that an ideal gas model would be able to fit in this case. Thus I do not know if any one would be able to give you an answer.
