Two molar of He gas (gamma=5//3) are initially at temp 27^(@)C and occupy a volume of 20 litres. The gas is first expanded at constant pressure untill its volume is doubled. then it undergoes and reversible adiabatic change, unit the volume become 110 lit, then predict the value of T//1000 ( where T is the final temeperature ((4)/(11))^(2//3)=((1)/(2)) |
