If the rms speed of methane gas in the Jupiter’s atmosphere is 471.8 m s^-1, show that the surface temperature of Jupiter is sub-zero.

At a g_ntemperature equal masses of monoatomic & diatomic gases are supplied equal quantities of heat. Which of the two gases will suffer a larger temperature rise?

Calculate the temperature at which the rms velocity of a gas triples its value at S.T.P.

Part - B

Generic 5 - Answer All Question

0.014 kg of nitrogen is enclosed in a vessel at a temperature of 27°C. How much heat has to be 'transferred to double the rms speed of its molecules.

Derive Meyer's relation.

A room contains oxygen and hydrogen molecules in the ratio 3:1. Th e temperature of the room is 27°C. The molar mass of 02 is 32 g mol-1 and for H₂ 2 g mol^-1. The value of gas constant R is 8.32 J mol^-1 K^-1.
Calculate
(a) rms speed of oxygen and hydrogen molecule
(b) Average kinetic energy per oxygen molecule and per hydrogen molecule
(c) Ratio of average kinetic energy of oxygen molecules and hydrogen molecules.
Obtain the relation between the pressure and average kinetic energy.
