A perfect gas goes from state A to another state B by absorbing $$8\times {{10}^{5}}J$$ of heat and doing $$6.5\times {{10}^{5}}J$$ of external work. It is now transferred between the same two states in another process in which it absorbs $${{10}^{5}}J$$ of heat. Then in the second process [BHU 1997]

TuteeHUB · Answer

Work done on gas is $${{10}^{5}}J$$

TuteeHUB · Answer

Work done by gas is $${{10}^{5}}J$$

1.	A perfect gas goes from state A to another state B by absorbing \[8\times {{10}^{5}}J\] of heat and doing \[6.5\times {{10}^{5}}J\] of external work. It is now transferred between the same two states in another process in which it absorbs \[{{10}^{5}}J\] of heat. Then in the second process [BHU 1997]
A.	Work done on the gas is \[0.5\times {{10}^{5}}J\]
