Problem $4-63$

A $3m^3$ rigid tank contains hydrogen at $250$ kPa and $550$K$.$ The hydrogen gas is now cooled until the temperature drops to $350$ K $.$

Determine

a$)$ Simplify the rate version of the $1^{st}$ Law of thermodynamics. Explain your assumptions.

b$)$ Determine if hydrogen can be treated as an ideal gas at these temperatures and pressures.

c$)$ The mass of hydrogen in the tank

d$)$ The final pressure in the tank

e$)$ the amount of heat transfered
