$P-V$ plots for two gases during adiabatic process are shown in the figure. Plots $1$ and $2$ should correspond respectively to
$He$ and ${O_2}$
${O_2}$ and $He$
$He$ and $Ar$
${O_2}$ and ${N_2}$
Why does a gas get heated on compression ?
Adiabatic modulus of elasticity of a gas is $2.1 \times {10^5}N/{m^2}.$ What will be its isothermal modulus of elasticity $\left( {\frac{{{C_p}}}{{{C_v}}} = 1.4} \right)$
If $\gamma $ denotes the ratio of two specific heats of a gas, the ratio of slopes of adiabatic and isothermal $PV$ curves at their point of intersection is
A tyre filled with air $({27^o}C,$ and $2$ atm) bursts, then what is temperature of air ....... $^oC$ $(\gamma = 1.5)$
The figure, shows the graph of logarithmic reading of pressure and volume for two ideal gases $A$ and $B$ undergoing adiabatic process. From figure it can be concluded that
