Adiabatic transformation .- + /2 - NiT . 1/ 2 PE = Airs is compressed mainly with diatomic molecules * = 5 (22 0 C ) = 73 OCIn a Diesel engine, atmospheric air at temperature 22C is quickly compressed to about 1/20 of its intial volume. Estimate the temperature of the air after compression and explain (to yourself) why a Diesel engine does not require spark plugs. Give the answer in degrees Celsius, so you have a better feeling for it. (2% relative tolerance). M b.) (On your own) Most diesel engines in trucks have "glow plugs" to help heat the gas. When might these be important
