Two statements are given below.

Statement I : Viscosity of liquid decreases with increase in temperature.

Statement II : The units of viscosity coefficient are pascal.

The correct answer is

What is the kinetic energy (in $\mathrm{J} \mathrm{mol}^{-1}$ ) of one mole of an ideal gas (molar mass $=0.1 \mathrm{~kg} \mathrm{~mol}^{-1}$ ) if its rms velocity is $4 \times 10^2 \mathrm{~ms}^{-1}$ at $T(\mathrm{~K})$ ?

Two statement are given below.

Statement I : The ratio of the molar volume of a gas to that of an ideal gas at constant temperature and pressure is called the compressibility factor.

Statement II : The rms velocity of a gas is directly proportional to square root of $T(\mathrm{~K})$.

The correct answer is

At 133.33 K . the rms velocity of an ideal gas is $$ \left(M=0.083 \mathrm{~kg} \mathrm{~mol}^{-1} ; R=8.3 \mathrm{~J} \mathrm{~mol}^{-1} \mathrm{~K}^{-1}\right) $$
