In a diesel engine, the piston compresses air at 302 K to a volume that is 0.0628 of the original volume and a pressure that is 48.2 times the original pressure. What is the temperature of the air after the compression?

Ok I know I have the temputure of the engine but how do i use that to find the tempure of the air after the compression Would N = PV/kT be a good formula to use.

    Yes, you can make the assumption of the ideal gas law.

  • physics -

    ok I used the Ideal gas fromula by
    saying (48.2)(.0628)/1.38*10^-23)(302K)
    I got a number N but it does seem to be correct and how would I use N to find the temp. of the air after compression?
