$$10 \mathrm{~g}$$ each of $$\mathrm{CH}_4$$ and $$\mathrm{O}_2$$ are kept in cylinders of same volume under same temperature, give the pressure ratio of two gases

The volume-temperature graphs of a given mass of an ideal gas at constant pressures are shown below. What is the correct order of pressures?

How will raise in temperature affects the viscosity of liquids and gases?

The given graph represents the variation of compressibility factor (Z) = $$\frac{pV}{nRT}$$, for three real gases A, B and C. Identify the only incorrect statement.

Equal masses of methane and oxygen are mixed in an empty container at 25$$^\circ$$C. The fraction of the total pressure exerted by oxygen is

Which of the following statements on critical constants of gases are correct?

I. Larger the T_c/p_c value of a gas, larger would be the included volume.

II. Critical temperature (T_c) of a gas is greater than its Boyle temperature (T_B).

III. At the critical point in the van der Waals' gas isotherm, $${\left( {{{\partial p} \over {\partial {V_m}}}} \right)_{{T_c}}} = 0$$
