A cylindrical flask is fitted with an airtight piston that is free to slide up and down, as shown in the figure(Figure 1) . A mass rests on top of the piston. The initial temperature of the system is 320K and the pressure of the gas is held constant at 137kPa . The temperature is now increased until the height of the piston rises from 23.4 cm to 25.0cm.
What is the final temperature of the gas? [T=? (k)]
