The condition $dQ = dU$ (heat supplied equals the increase in internal energy) is true for which of the following processes?

In an isobaric expansion of an ideal gas,which of the following is zero?

Two cylinders contain the same amount of an ideal monatomic gas. The same amount of heat is given to both cylinders. If the temperature rise in cylinder $A$ is $T_0$,then the temperature rise in cylinder $B$ will be:

Calculate the work done when the volume of a gas increases by $0.25\,m^3$ at a constant pressure of $10^3\,N/m^2$.

The thermodynamic process in which the work done on or by the gas is zero is:

An ideal gas having pressure $P$, volume $V$, and temperature $T$ undergoes a thermodynamic process in which $dW = 0$ and $dQ < 0$. Then, for the gas
