The figure below shows the plot of PV/ nT versus P for oxygen gas at two different temperatures

If pressure of CO₂ (real gas) in a container is given by P= (RT/ 2V-b) – (a/ 4b^2), then mass of the gas in container is2

Two balloons are filled, one with pure He gas and the other by air, respectively. If the pressure and temperature of these balloons are same, then the number of molecules per unit volume

Increase in temperature of a gas filled in a container would lead to

The volume (V) of a monatomic gas varies with its temperature (T), as shown in the graph. The ratio of work done by the gas, to the heat absorbed by it, when it undergoes a change from state A to state B, is

The gas mixture consists of 3 moles of oxygen and 5 moles of argon at temperature T. Considering only translational and rotational modes, the total internal energy of the system is

Two kg of a monoatomic gas is at a pressure of 4×10^4 N/m². The density of the gas is 8 kg/m³. What is the order of energy of the gas due to its thermal motion

Three perfect gases at absolute temperature T1, T2 and T3 are mixed. The masses of molecules are m1, m2 and m3 and the number of molecules are n1, n2 and n3 respectively. Assuming no loss of energy, the final temperature of the mixture is

A 15g mass of nitrogen gas is enclosed in a vessel at a temperature 27°C. Amount of heat transferred to the gas, so that rms velocity of molecules is doubled, is about [take R = 8.3J/k mole]

One kg of a diatomic gas is at a pressure of 8×10^4 N/m². The density of the gas is 4 kg/m³. What is the energy of the gas due to its thermal motion
