164172 An ideal gas heat engine operates in a carnot cycle between \(227^{\circ} \mathrm{C}\) and \(127^{\circ} \mathrm{C}\). It absorbs \(6 \mathrm{kcal}\) at the higher temperature. The amount of heat (in kcal) converted into work is equal to :

1 1.6
2 1.2
3 4.8
4 3.5

164173 Choose the incorrect statement related to a isobaric process:

1 \(V / T=\) constant
2 \(\mathrm{W}=\mathrm{P} \Delta \mathrm{V}\)
3 Heat given to a system is used up in raising the temperature only
4 Work done is \(\mu R \Delta T\)
