## Homework Statement

Calculate a value of R, specific gas constant for air, from the values you have.

Also calculate the work done in the compression process.

## Homework Equations

Pv = RT

ρ

_{air}= 1.2 kg/m^3

## The Attempt at a Solution

Have P,V and T data from an adiabatic compression. I think I need initial values for these but not sure what else.

Also we have been given the density for air so the mass of the air in the tube, m = ρ*V = 2.903172 x 10^-4 kg. However this will change surely as volume decreases?
