The compressive ratio of a certain diesel engine is `15`. This means that air in the cylinder is compressed to 1/15 of its initial volume. If the initial pressure is `1.0 xx10^5 Pa` and the initial temperature is 300 K, find the final pressure and temperature after compression. Air is mostly a mixture of oxygen and nitrogen and y = 1.4`
