The change in volume $V$ with respect to an increase in pressure $P$ has been shown in the figure for a non-ideal gas at four different temperatures ${T_1},\,{T_2},\,{T_3}$ and ${T_4}$. The critical temperature of the gas is
A${T_1}$
B${T_2}$
C${T_3}$
D${T_4}$

B${T_2}$
b At critical temperature, the horizontal part of the $P-V$ curve ends, as is the case at temperature $T_2$.

An ideal gas initially at pressure $1$ bar is being compressed from $30 \,m ^{3}$ to $10\, m ^{3}$ volume and its temperature decreases from $320\, K$ to $280\, K$. then find final pressure of gas (in bar)
The temperature of $5$ moles of a gas which was held at constant volume was changed from ${100^o}C$ to ${120^o}C$. The change in internal energy was found to be $80$ Joules. The total heat capacity of the gas at constant volume will be equal to ...... $J/K$
The temperature, at which the root mean square velocity of hydrogen molecules equals their escape velocity from the earth is closest to : [Boltzmans Constant $k_B = 1.38\times10^{-23}\, J / K$ Avogadro number $N_A = 6.02\times10^{26}\, / kg$ Radius of Earth $: 6.4\times10^6\, m$ Gravitation acceleration on Earth $= 10\, ms^{-2}$]
The air density at Mount Everest is less than that at the sea level. It is found by mountaineers that for one trip lasting a few hours, the extra oxygen needed by them corresponds to $30,000\ cc$ at sea level (pressure $1$ atmosphere, temperature $27^oC).$ Assuming that the temperature around Mount Everest is $-73^oC$ and that the oxygen cylinder has capacity of $5.2\ litre,$ the pressure at which $O_2$ be filled (at site) in cylinder is ..... $atm$
Pressure versus temperature graph of an ideal gas at constant volume $V$ of an ideal gas is shown by the straight line $A$. Now mass of the gas is doubled and the volume is halved, then the corresponding pressure versus temperature graph will be shown by the line
$7$ mole of certain monoatomic ideal gas undergoes a temperature increase of $40 K$ at constant pressure. The increase in the internal energy of the gas in this process is$....J$ (Given $R =8.3 JK ^{-1} mol ^{-1}$ )
The specific heat of a gas at constant volume is $21.2\, J/mole/°C.$ If the temperature is increased by $1°C$ keeping the volume constant, the change in its internal energy will be ...... $J$
