$A$ diatomic gas $(\gamma = 1.4)$ does $100 \ J$ of work when it is expanded isobarically. Then the heat given to the gas is . . . . . . $J$.

$A$ monoatomic gas is supplied heat $Q$ very slowly while keeping the pressure constant. The work done by the gas will be

Two kg of water is converted into steam by boiling at atmospheric pressure. The volume changes from $2 \times 10^{-3} \ m^3$ to $3.34 \ m^3$. The work done by the system is about ....... $kJ$.

The heat energy supplied to a diatomic gas at constant pressure is $210 \,J$. Then, the work done by the gas is: (in $\,J$)

Write the expression for the work done by an ideal gas in an isobaric process.

The volume $(V)$ of a monatomic gas varies with its temperature $(T)$,as shown in the graph. The ratio of work done by the gas to the heat absorbed by it,when it undergoes a change from state $A$ to state $B$,is
