A rigid tank whose volume is unknown is divided into two parts by a partition. One side of the tank contains an ideal gas at 915C. The other side is evacuated and has a volume twice the size of the part containing the gas. The partition is now removed and the gas expands to fill the entire tank. Heat is now transferred to the gas until the pressure equals the initial pressure. Determine the final temperature of the gas. Ideal gas TC V Evacuated 2V1 The final temperature is ]C.
