Chapter 2, Problem 113P

A rigid tank contains an ideal gas at $300\text{kPa}$ and $\text{600}\text{}\text{K}\text{.}$ Half of the gas is withdrawn from the tank and the gas is at $\text{100}\text{}\text{}\text{kPa}$ at the end at the process. Determine (a) the final temperature of the gas and (b) the final pressure if he mass were withdrawn from the tank and the same final temperature were reached at the end at the process.
