• A gas of `gamma=1.4` and initial temperature `0^(@)C` is suddenly compressed to `1//5th` its original volume. Calculate the rise in temperature.
• A certain mass of a gas is taken at `0^(@)C` in a cylinder whose walls are perfect insulators. The gas is compressed (a) slowly, (b) suddenly till its pressure is increased to 20 times the initial pressure `(gamma=1.4)`. Calculate the final temperature in each case.
• A cubic metre of dry air at NTP is allowed to expand to 5 cubic metres (i) isothermally, (ii) adiabatically. Calculate in each cae, the pressure, temperature and work done. (`gamma=1.4` and `1 atm=1.013xx10^(5)Nm^(-2)`)
• A gas at constant pressure `P_1, volume V_1` and temperture `T_1` is suddenly compressed to `V_1/2` and then slowly expanded to `V_1` again.Find the final temperature and pressure.
