An ieal 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
$4.8 \times {10^4}\,cal$
$3.5 \times {10^4}\,cal$
$1.6 \times {10^4}\,cal$
$1.2 \times {10^4}\,cal$
Heat is supplied to a di-atomic gas at constant pressure. The ratio of $\Delta Q : \Delta U : \Delta W$ is
In the cyclic process shown on the $P -V$ diagram, the magnitude of the work done is
An ideal gas heat engine operates in a Carnot's cycle between ${227^o}C$ and ${127^o}C$. It absorbs $6 × 10^4 \,J$ at high temperature. The amount of heat converted into work is ....
If $R =$ universal gas constant, the amount of heat needed to raise the temperature of $2\, mol$ of an ideal monoatomic gas from $273\, K$ to $373\, K$ when no work is done is
A thermodynamic system is taken through the cycle $PQRSP$ process. the net work done by the system is...... $J$
