1.	A gas is compressed at a constant pressure of 50N//m^(2) from a volume 4m^(3). Energy of 100 J is then added to the gas by heating. Its internal energy is ………….. .
Answer» INCREASED BY400 J increased by 200 J increased by 100 J decreased by 200 J Solution :`DeltaU=DeltaQ-DeltaW=DeltaQ-PDeltaV=100-50(4-10)=400J`
