$1m^3$ of gas undergoes an adiabatic compression from 1 bar to 10 bar. Determine the work required per kg, if its ratio of specific heats is 1.4.
I know that 1 bar is equal $1$x$10^5$Pa. I also know that $PV^k=constant$. I also know that through the adiabatic compression process that work, $w=[m*R*(T2-T1)]/(1-k)$ . I tried using this equation. However how can I calculate the work using this equation if no mass has been specified and no change in temperature?
