Two identical syringes are filled to the same volume at the same temperature and pressure. If one

syringe is filled with chlorine gas and the other with nitrogen gas
A. the syringe filled with nitrogen gas contains more moles of gas.
B. the syringe filled with nitrogen gas contains more grams of gas.
C. the different gases have the same average kinetic energy.
D. the molecules of chlorine gas have a higher average velocity than the molecules of nitrogen gas.

Could someone explain why the answer is C?

Answer 1

The temperature is the same, so the amount of kinetic energy will also be the same.
