Please help me with the answers of these questions: (a) Suggest why the expansion of air into a region of low pressure is an endothermic process? (b) Gases like CO2 can be liquified at room temp just by pressuring them. Why does the application of pressure causes the gas to liquify? (c) Gases can only be liquified by pressure alone if their temp is below their critical temp Tc. Above Tc, no amount of pressure will liquify a gas. Give an explanation.

    (b) becos as we apply pressure it causes the gas to move towards liquid or its critical state where its kinetic energy is decreased along with the temperature.

    in part (d) you just have to add that every gas has its critical state , if it crosses that state , a gas cannot liquify no matter how much pressure is applied.
