Question

effect of temperature on most probable velocity​

Answer 1

We can say that from the equation that the most probable velocity of gas molecules increases with the increase in temperature. At higher temperature, large numbers of molecules will acquire greater amounts of kinetic energy and they move very fast hence their speed increases.

Answer 2

Frictional force causes a lot of losses in general upkeep and wear and tear of machinery. Hence it is considered as a evil. But almost all crucial tasks cannot be carried out without the presence of friction. ... Hence it is considered as a necessary evil .
