An expandable cylinder has its top connected to a spring with force constant 2.00 x 103 N/m (see figure below). The cylinder is filled with 4.00 L of gas with the spring relaxed at a pressure of 1.00 atm and a temperature of 20.0°C. wwwww. T= 20.0°C T (a) If the lid has a cross-sectional area of 0.0100 m² and negligible mass, how high will the lid rise when the temperature is raised to T₁ = 260°C? ст (b) What is the pressure of the gas at T = 260°C?
