Kinetic Theory ...

The average kinetic energy of hydrogen molecules at 300 K is E. At the same temperature, the average kinetic energy of oxygen molecules will be

The temperature at which the average translational kinetic energy of a molecule is equal to the energy gained by an electron in accelerating from rest through a potential difference of 1 volt is

The kinetic energy of one g-mole of a gas at normal temperature and pressure is (R = 8.31 J/mol-K)

N molecules each of mass m of gas A and 2N molecules each of mass 2m of gas B are contained in the same vessel at temperature T. The mean square of the velocity of molecules of gas B is v² and the mean square of x component of the velocity of molecules of gas A isw². The ratio w² / v²is

A gas is filled in a cylinder, its temperature is increased by 20% on kelvin scale and volume is reduced by 10%. How much percentage of the gas will leak out

The air density at Mount Everest is less than that at the sea level. It is found by mountaineers that for one trip lasting a few hours, the extra oxygen needed by them corresponds to 30,000 cc at sea level (pressure 1 atmosphere, temperature 27°C). Assuming that the temperature around Mount Everest is –73 ° C and that the oxygen cylinder has capacity of 5.2 litre, the pressure at which O₂ be filled (at site) in cylinder is

1/2 mole of helium gas is contained in a container at S.T.P. The heat energy needed to double the pressure of the gas, keeping the volume constant (specific heat of the gas = 3 J g^–1K^–) is

70 calories of heat are required to raise the temperature of 2 moles of an ideal gas at constant pressure, from 30°C to 35°C. The amount of heat required to raise the temperature of same gas through the same range (30°C to 35°C) at constant volume (R = 2 cal/mol/K) is

A box containing N molecules of a perfect gas at temperature T₁ and pressure P₁. The number of molecules in the box is doubled keeping the total kinetic energy of the gas same as before. If the new pressure is P₂ and temperature T₂, then
