An expandable cylinder has its top connected to a spring with force constant 2.00 x 10 N/m (see figure below). The cylinder is filled with 4.50 L of gas with the spring relaxed at a pressure of 1.00 atm and a temperature of 20.0 C. k T = 20.0'C (a) If the lid has a cross-sectional area of 0.0100 mand negligible mass, how high will the lid rise when the temperature is raised to T = 280 C? cm (b) What is the pressure of the gas at 7 = 280 C?
