Suppose a 3000 cm3 container holds 7.0 g of nitrogen gas at a pressure of 200 kPa. The gas can be heated at constant pressure if a piston moves outward to let the gas expand as it's heated. Alternatively, the gas can be heated at constant volume if the piston is locked in place to prevent expansion.
We know starting temperature is 290 K
1, Returning to the starting conditions, the gas is heated but the piston is allowed to move in a way that keeps the pressure constant. What is the final temperature if the gas is heated until the volume doubles?
