The molecules of water have more energy as compared to molecules of ice at same temperature. Justify this statement.

The density of water at 0^@C is more than that of ice at the same temperature. Why?

ļn an open room at atmospheric pressure, the total kinetic energy of all the air molecules is more when the room is warm than the total kinetic energy of the molecules in the same room when it is cool. Justify this statement.

Molecules of CO at moderate temperature have energy equal to

"The total kinetic energy of the molecules in an ideal gas with a volume V at pressure P and temperature T is equal to the total kinetic energy of the molecules present in the same volume of another ideal gas at the same pressure and at temperature 2T"-Justify the statement.

Statement I: The root mean square speeds of the molecules of different ideal gases at the same temperature are the same. Statement II: The average translational kinetic energy of molecules of different ideal gas are same at the same temperature.

molecules have 'rms' velocity 2km/s. The 'rms' velocity of the oxygen molecules at same temperature is.

What is the ratio of the total energy of all the molecules of one mole of O_(2) to the total energy of all the molecules of two moles of helium at the same temperature?

Which of the following molecules will have the higher value of most probable speed at the same temperature , N_2 or Cl_2 ? Justify.
