A cylindrical flask is fitted with an airtight piston that is free to slide up and down. A mass rests on top of the piston. The initial temperature of the system is 486 K and the pressure of the gas is held constant at 19 kPa. The temperature is now increased until the height of the piston rises from 23.4cm to 35.6 cm. What is the final temperature of the gas?
