An ideal gas goes through a reversible cycle $a\to b\to c\to d$ has the $V – T$ diagram shown below. Process $d\to a$ and $b\to c$ are adiabatic….  The corresponding $P – V$ diagram for the process is (all figures are schematic and not drawn to scale)

During an adiabatic process, the pressure of a gas is found to be proportional to the cube of its temperature. The ratio of  $\frac{{{C_P}}}{{{C_V}}}$  for the gas is

A cycle tyre bursts suddenly. This represents an

A gas is suddenly compressed to one fourth of its original volume. What will be its final pressure, if its initial pressure is $P$

A monoatomic gas at pressure $P$ and volume $V$ is suddenly compressed to one eighth of its original volume. The final pressure at constant entropy will be $…..P$
