Two different gases are stored in separate closed containers. if both gases have a temperature of 50°c, which statement is true?

a)the thermal energies of gas molecules in the two containers are unrelated.
b)the gas molecules in both containers will absorb heat from the surroundings.
c)the molecules in one gas will transfer energy to the molecules in the other gas.
d)the gas molecules in both containers have the same average kinetic energy.

Option D: The gas molecules in both containers have the same average kinetic energy.

Explanation:

The average kinetic energy depends upon the temperature of the gas. Hence, even if the two gases are different but have same temperature, the average kinetic energy would be same of both the gases.

B. The gas molecules in both containers will absorb heat from the surrounding- we do not the temperature of the surroundings, so we cannot say about this.

C. The molecules in one gas will transfer energy to the molecules in the other gas.- gases are stored in separate containers. Also the temperature of the two gases is same. so, there will be no transfer of energy.

A. The thermal energies of gas molecules in the two containers are unrelated- The thermal energies would be related because thermal energy is dependent on the temperature of the two gases. Since, the two gases have same temperature, therefore the thermal energies of the two would be related.

Hence, the correct option is D.
