An ideal heat engine operates on Carnot cycle between $227\,^oC$ and $127\,^oC$. It absorbs $6 \times 10^4\, cal$ at the higher temperature. The amount of heat converted into work equals to
$4.8 \times {10^4}\,cal$
$3.5 \times {10^4}\,cal$
$1.6 \times {10^4}\,cal$
$1.2 \times {10^4}\,cal$
Which of the following is correct in terms of increasing work done for the same initial and final state
A termodynamic system is taken through the closed cycle $PQRSP$ process. The net work done by the system is ...... $J$
In the indicator diagram (in figure), net amount of work done will be
A cyclic process $ABCA$ is shown in $PT$ diagram. When presented on $PV$, it would be
In thermodynamic process pressure of a fixed mass of gas is changed in such a manner that the gas releases $30$ joule of heat and $18$ joule of work was done on the gas. If the initial internal energy of the gas was $60$ joule, then, the final internal energy will be ..... $J$
