Is it possible to increase the temperature of a gas without adding heat to it? Explain.
It is possible to increase the temperature of a gas without adding heat to it, during adiabatic compression the temperature of a gas increases while no heat is given to it. For an adiabatic compression, no heat is given or taken out in adiabatic process. Therefore, ΔQ=0 According to the first law of thermodynamics, ΔQ=ΔU+ΔW ΔU=−ΔW(ΔQ=0) In compression work is done on the gas, i.e. work done is negative. Therefore, ΔU= Positive Hence, internal energy of the gas increases
