In a gas, 5 molecules have speed 150 m/s, 170 m/s, 170 m/s, 180 m/s, 190 m/s. Ratio of V_r_m_s to V_m_e_a_n is nearly
Root mean square velocity -
- wherein
R = Universal gas constant
M = molar mass
P = pressure due to gas
= density
Average speed of molecule of a gas -
- wherein
K = Boltzmann's Constant
m = mass of a molecule
R = Universal gas constant
T = temperature
Ratio = 1
