NEET Practice Questions (MCQs) with Answers & Solutions

The ratio of the specific heats C_P/C_V=γ in terms of degrees of freedom (n) is given by -

Two vessels separately contain two ideal gases A and B at the same temperature, the pressure of A being twice that of B. Under such conditions, the density of A is found to be 1.5 times the density of B. The ratio of molecular weight of A and B is:

A monoatomic gas at a pressure p, having a volume V expands isothermally to a volume 2 V and then adiabatically to a volume 16 V. The final pressure of the gas is: (take  γ=5/3)

The mean free path of molecules of a gas, (radius r) is inversely proportional to :

The molar specific heats of an ideal gas at constant pressure and volume are denoted by C_P and C_V respectively. If γ=C_P/C_V and R is the universal gas constant, then CV is equal to

If ${\mathrm{C}}_{\mathrm{p}}$ and ${\mathrm{C}}_{\mathrm{v}}$ denote the specific heats (per unit mass) of an ideal gas of molecular weight M

Two gases of equal mass are in thermal equilibrium. If ${\mathrm{P}}_{\mathrm{a}}, {\mathrm{P}}_{\mathrm{b}}$ and ${\mathrm{V}}_{\mathrm{a}}$ and ${\mathrm{V}}_{\mathrm{b}}$ are their respective pressures and volumes, then which relation is true

The vapor of a substance behaves as a gas :

The temperature below which gas should be cooled, before it can be liquified by pressure only is termed as :

The mean free path of gas molecules depends on (d = molecular diameter)
