## Homework Statement

A mass of gas occupies a volume of 4.3L at a pressure of 1.2 atm and a temperature of 310K. It is compressed adiabatically to a volume of 0.76L.Determine (a)the final pressure and (b) the final temperature,assuming the gas to be an ideal gas for which gamma = 1.4.

## Homework Equations

gamma = Cp/Cv

w = (1/gamma-1)(p1v1-p2v2)

w=-Cv(deltaT)

## The Attempt at a Solution

I'm not really sure where to start but haf wote out everything and have converted all to basic SI units,explanation of solution of this question would be much appreciated.
