The $PV$ diagram shows four different possible reversible processes performed on a monatomic ideal gas. Process $A$ is isobaric (constant pressure). Process $B$ is isothermal (constant temperature). Process $C$ is adiabatic. Process $D$ is isochoric (constant volume). For which process$(es)$ does the temperature of the gas decrease?
Process $A$ only
Process $C$ only
Only Processes $C$ and $D$
Only Processes $B$, $C$ and $D$
Match List $I$ with List $II$ :
List $I$ | List $II$ |
$A$ Isothermal Process | $I$ Work done by the gas decreases internal energy |
$B$ Adiabatic Process | $II$ No change in internal energy |
$C$ Isochoric Process | $III$ The heat absorbed goes partly to increase internal energy and partly to do work |
$D$ Isobaric Process | $IV$ No work is done on or by the gas |

What is an adiabatic process ? Derive an expression for work done in an adiabatic process.
A sample of gas at temperature $\mathrm{T}$ is adiabatically expanded to double its volume. Adiabatic constant for the gas is $\gamma=3 / 2$. The work done by the gas in the process is : $(\mu=1 \mathrm{~mole})$
Jet aircrafts fly at altitudes above $30000 \,ft$, where the air is very cold at $-40^{\circ} C$ and the pressure is $0.28 \,atm$. The cabin is maintained at $1 \,atm$ pressure by means of a compressor which exchanges air from outside adiabatically. In order to have a comfortable cabin temperature of $25^{\circ} C$, we will require in addition
A gas may expand either adiabatically or isothermally. A number of $P-V$ curves are drawn for the two processes over different range of pressure and volume. It will be found that
