The mass of gas particle affects the rate of effusion by decreasing the rate as the mass increases. This describe by the Graham's Law of Effusion where the rate of effusion is inversely proportional to the square root of the molar mass of a substance. Hope this helps.
<span>To convert between mass and number of moles, you can use the molar mass of the <span>substance.
Hope I helped : )

Answer: Option (d) is the correct answer.
Explanation:
In winter's, temperature of atmosphere is low and due to this molecules of air present in the tire come closer to each other as they gain potential energy and loses kinetic energy.
Hence, air pressure decreases and there is need to fill more air in the tire.
Whereas is summer's, temperature is high so, molecules of air inside the tire gain kinetic energy and move rapidly from one place to another due to number of collisions. So, air pressure increases and there is no need to fill more air inside the tire.
Thus, we can conclude that the temperature is lower, so the air inside the tires contracts.
