The average molecular speed is greatest in case of a gas sample of :

A sample of gas measured at 20^(@)C C and 4.0 atm is heated to 40^(@)C at constant volume. Which statement(s) is (are) true of the gas after heating relative to its initial satate? (P) The average molecular kinetic energy is increased. (Q) The average molecular speed is unchanged. (R) The pressure of the gas is increased to 8.0 atm. (S) The number of molecular collisions per second is unchanged.

The average speed of gas molecules is equal to

The average speed of gas molecules is equal to :

A hypothetical gas sample has its molecular speed distribution graph as shown in the figure. The speed (u) and (dN)/(du) have appropriate units. Find the root mean square speed of the molecules. Do not worry about units.
