The drawing shows an ideal gas confined to a cylinder by a massless piston that is attached to an ideal spring. Outside the cylinder is a vacuum. The cross-sectional area of the piston is A = 2.50 x 10-3 m2. The initial pressure, volume, and temperature of the gas are, respectively, Po, Vo = 6.00 x 10-4 m and To = 273 K, and the spring is initially stretched by an amount xo = 0.094 m with respect to its unstrained length. The gas is heated, so that its final pressure, volume, and temperature are Pr, V, and T and the spring is stretched by an amount Xf = 0.11 m with respect to its unstrained length. What is the final temperature of the gas? - Piston Tf= e Textbook and Media
