Question
.The r.m.s. velocity of a gas is*1 point(a) directly proportional to the density of the gas.(b) inversely proportional to the density of the gas.(c) directly proportional to the square of density.(d) inversely proportional to the square root of the density of the gas
Solution
The r.m.s. velocity of a gas is determined by the kinetic theory of gases. According to this theory, the r.m.s. velocity is directly proportional to the square root of the temperature of the gas. Therefore, the r.m.s. velocity is not directly related to the density of the gas. Hence, the correct answer is not mentioned in the given options.
