Kinetic Theory Of Gases Mock Tests

The rms speed of molecules of a gas at 27°C and 1 atmosphere pressure is 200 m/s. If the temperature is increased to 927°C at the same pressure, the new rms speed will be:

The rms speed of molecules of a gas at temperature T is v. If the temperature is doubled, the new rms speed will be:

The root mean square speed of gas molecules at 27°C is v. At what temperature will the rms speed become 2v?

The rms speed of oxygen molecules at 27°C is 500 m/s. If the temperature is increased to 127°C while keeping the pressure constant, the new rms speed will be approximately:

The average kinetic energy of a molecule of an ideal gas at 300 K is: (k_B = 1.38 × 10⁻²³ J/K)

The rms speed of molecules of a gas at temperature T and pressure P is v. If the temperature is doubled and the pressure is reduced to half, the new rms speed will be:

Two samples of ideal gas A and B are at the same temperature. The molecular mass of A is twice that of B. The ratio of their rms speeds vₐ/vᵦ is:

The kinetic energy of a gas molecule at 27°C is K. At 327°C, its kinetic energy will be:
