In the following P-V diagram of an ideal gas, two adiabates and two isotherms at T₁=300K and T₂=200K are shown. Values are VA=2, VB=8, VC=16. Find VD. 

Two balloons are filled with pure gases and other with air respectively. If the pressure and temperature of these balloons are same, then the number of molecules per unit volume is:
Two gases occupy two containers A and B. The gas in A, of volume 0.10 m³, exerts a pressure of 1.40 MPa and that in B of volume 0.15 m³ exerts a pressure of 0.7 MPa. The two containers are united by a tube of negligible volume and the gases are allowed to intermingle. Then if the temperature remains constant, the final pressure in the container will be (in MPa)
A vessel containing 1 more of \( O_2 \) gas (molar mass 32) at temperature \( T \). The pressure of the gas is \( p \). An identical vessel containing one mole of He gas (molar mass 4) at temperature 2T has a pressure of –
For an isothermal expansion of a perfect gas, the value of \( \frac{\Delta P}{P} \) is equal to:
In the equation PV^γ=constant, the value of γ is unity. Then the process is
