In a given process for an ideal gas,$dW = 0$ and $dQ < 0$. Then for the gas:

$A$ certain amount of heat energy is supplied to a monoatomic ideal gas which expands at constant pressure. What fraction of the heat energy is converted into work?

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:

Derive the expression for work done by a gas during an isobaric process (constant pressure).

Which one of the following equations specifies an isobaric process?
$[Q=$ heat supplied; $\Delta P, \Delta V$ and $\Delta T$ are change in pressure,volume,and temperature respectively.]

The ratio of work done by an ideal monoatomic gas to the heat supplied to it in an isobaric process is
