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 = 2.50x 10ma. The initial pressure, volume, and temperature of the gas are, respectively. Po. Vo= 6.00 x 10"#m and To- 273 K. and the spring is initially stretched by an amount x - 0.092 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 x, = 0.12 m with respect to its unstrained length. What is the final temperature of the gas? T 402 5 K
