Q. An expandable cylinder has its top connected to a spring with force constant 2 x10^3 N/m. The cylinder is filled with 6 L of gas with the spring relaxed at a pressure of 1.0 atm and a temperature of 20°C.
(1) If the lid has a cross-sectional area of 0.010m2 and negligible mass, how high will the lid rise when the temperature is raised to Tf = 270°C?
(2) What is the pressure of the gas at Tf = 270°C?
