A cylinder of cross-sectional area 11 cm2 is fitted with a piston, which is connected to a spring with a spring constant of 1250 N/m, as shown in the figure. The cylinder is filled with 0.0050 mole of a gas. At room temperature (23 °C), the spring is neither compressed nor stretched. How far is the spring compressed if the temperature of the gas is raised to 135 °C? (Assume the pressure in the volume containing the spring stays constant at atmospheric pressure.)
