1A Jaguar XK8 convertible has an eight-cylinder engine. At the beginning of its compression stroke, one of the cylinders contains 498 cm^3 of air at atmospheric pressure (1.01 x 10 ^5 Pa) and a temperature of 27.0 C. At the end of the stroke, the air has been compressed to a volume of 46.3 cm^3 and the gauge pressure has increased to 2.8 x 10 ^6 Pa . What is the final temperature? pv=nrt T0=300K P0=1.01 x 10 ^5 Pa V0=498 cm^3 Tf=? Pf=2.8 x 10 ^6 Pa . Vf=46.3 cm^3 So I set a a proportionality and I get Tf=Pf * Vf* T0/( P0 * V0) plug in the values and get about 773 K or 500 celsius but my answer is wrong.
