Which Factors Does Molecular Speed Depend On?

by

Which Factors Does Molecular Speed Depend On? The speed of the molecules in a gas is proportional to the temperature and is inversely proportional to molar mass of the gas. In other words, as the temperature of a sample of gas is increased, the molecules speed up and the root mean square molecular speed increases

What Are The Different Mechanisms For Diffusion?

What Are The Different Mechanisms For Diffusion? Diffusion can occur by two different mechanisms: interstitial diffusion and substitutional diffusion. Which diffusion mechanisms is the fastest? Interstitial diffusion is generally faster than vacancy diffusion because bonding of interstitials to the surrounding atoms is normally weaker and there are many more interstitial sites than vacancy sites to
