Consider a collision between oxygen molecule and hydrogen molecule in a mixture of oxygen and hydrogen kept at room temperature. Which of the following are possible

Answer»

The KINETIC energies of both the MOLECULES increase 
The kinetic energies of both the molecules decrease 
The kinetic energy of the oxygen MOLECULE increases and that of the hydrogen molecule decreases 
The kinetic energy of the hydrogen molecule increases and that of the oxygen molecule decreases 

Solution :KE REDISTRIBUTE but `sum` KE remains same.
