the compression ratio of a certain diesel engine is 15 . this means that air in the cylinder is conpresssed to 1/15 th of initial volume . if the initial pressure is is 10^5 pascals and initial temperature is 300 k, find the final temperature and pressure . hint ( in adiabatic process the ideal gas equation become like this pv^gamma = K(constant) and here gamma = 1.4 in this question)
