Consider a short time span just before and after the spark plug in a gasoline engine ignites the fuel-air mixture and releases 1970 J of thermal energy into a volume of 47.6 cm3 that is at a gas pressure of 1.17 × 106 Pa. In this short period of time the volume of the gas can be considered constant.

(a) Treating the fuel-air mixture as a monatomic ideal gas at an initial temperature of 325 K, what is its temperature after ignition?

(b) What is the pressure in the gas after ignition?
