Four curves $A, B, C$ and $D$ are drawn in the adjoining figure for a given amount of gas. The curves which represent adiabatic and isothermal changes are
$C$ and $D$ respectively
$D$ and $C$ respectively
$A$ and $B$ respectively
$B$ and $A$ respectively
The pressure in the tyre of a car is four times the atmospheric pressure at $300 K$. If this tyre suddenly bursts, its new temperature will be $(\gamma = 1.4)$
The volume of an ideal gas $(\gamma=1.5)$ is changed adiabatically from $5$ litres to $4$ litres. The ratio of initial pressure to final pressure is:
A gas is suddenly compressed to $1/4$ th of its original volume at normal temperature. The increase in its temperature is ....... $K$ $(\gamma = 1.5)$
A mixture of gases at $STP$ for which $\gamma=1.5$ is suddenly compressed to $\frac{1}{9}$ th of its original volume. The final temperature of mixture is .......... $^{\circ} C$
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 |
