Question
Consider a collision between an argon molecule and a nitrogen molecule in a mixture of argon and nitrogen kept at room temperature. Which of the following are possible ?
Options
A.The kinetic energies of both the molecules decrease.
B.The kinetic energies of both the molecules increase
C.The kinetic energy of the argon molecule increases and that of the nitrogen molecules decrease.
D.The kinetic energy of the nitrogen molecules increases and that of the argon molecule decrease.
Solution
By energy conservation, energy loss by one molecule is equal to gain by other.
