The Diesel Engine

The SHC for air is 0.00121 J.kg-1.K-1 Given the volume of air is 500cm3, the density of air is 1.294kg.m-3, work out how much energy is required to compress the cylinder of air. (Hint, convert the volume of air to mass first!) Next, if the engine is running at 1000rpm, how much energy is needed to compress the air. Show your working.
