Keeping temperature constant if number of gaseous molecules are doubled in a container then what will be the changes in rms velocity, pressure & kinetic energy.

At which temperature does the kinetic energy of gas molecules become zero?

At what temperature will the rms speed of air molecules be double that at NTP?

For an ideal gas, C_(V)=(3)/(2)R . (a) What will be the change in internal energy (DeltaU) of 1 mole of an ideal gas if its temperature is increased by 4K at constant volume ? What would be DeltaU if the temperature of this gas is increased by the same amount of constant pressure? keeping pressure constant if the temperature of that same amount of gas is increased by 4K then what will be the change in internal energy (DeltaU) of that gas? (c) give reason for different values of DeltaU and DeltaH ?

If the temperature of 1 mol of an ideal gas is doubled then what will be the change in value of internal energy? Will it increase, decrease or remain the same?

A gas is kept in a closed containers at constant temperature. Keeping the temperature constant if some amount of the gas is incorporated.what will be the change in pressure?

At what temperature the average kinetic energy of the molecules of a perfect gas be doubled than that at 20^@C ?

In two identical gas containers, equal numbers of hydrogen and helium molecules are kept at the same temperature . What will be the ratio of their pressure?

Average kinetic energy of the atom of Hg vapour is 1000 cal*mol^(-1) . What will be the value of its rms velocity?

Keeping the temperature and diameter constant the length of a wire is made thrice. What change in the resistance of the wire will be seen ?

CO(g)+2H_2(g)iffCH_3OH(g) , for this reversible reaction at equilibrium Keeping temperature constant what will happen if (i) the volume of the container is halved (ii) the partial pressure of H_2 is halved (iii) He gas is introduced at constant temperature and pressure.
