Question

square root of the mean of the square of thr velocity of a large number of molecules is called​

Answer 1

Answer:

3RT

Explanation:

Root mean square velocity → The square root of the mean of squares of the velocity of individual gas molecules.

μ

R.M.S.

=

M

3RT

Whereas,

R is the gas constant.

T is the temperature (in K).

M is the molar mass of the gas.

Average velocity → The arithmetic mean of the velocities of different molecules of a gas at a given temperature.

μ

av.

=

πM

8RT

Whereas,

R is the gas constant.

T is the temperature (in K).

M is the molar mass of the gas.

Answer 2

Explanation:

3Rt is the correct answer of this question.
