Heat Equations for Special Processes & Molar Specific Heats
Piston air compressors are devices used to compress air to high pressures for storage in tanks. The device takes in air at atmospheric pressure (1 atm) and 18.0 °C. The compression is very fast such that it is assumed adiabatic. If the final volume is 0.120 of the initial volume, and air behaves like an ideal gas with γ = 1.40, determine the temperature and pressure at this instant of the compression.
