RMS Velocity given Pressure and Density Solution

STEP 0: Pre-Calculation Summary

Formula Used

Root Mean Square Speed = sqrt((3*Pressure of Gas)/Density of Gas)
C_RMS = sqrt((3*P_gas)/ρ_gas)
This formula uses 1 Functions, 3 Variables

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Root Mean Square Speed - (Measured in Meter per Second) - The Root Mean Square Speed is the value of the square root of the sum of the squares of the stacking velocity values divided by the number of values.
Pressure of Gas - (Measured in Pascal) - The pressure of Gas is the force that the gas exerts on the walls of its container.
Density of Gas - (Measured in Kilogram per Cubic Meter) - The Density of Gas is defined as mass per unit volume of a gas under specific conditions of temperature and pressure.

STEP 1: Convert Input(s) to Base Unit

Pressure of Gas: 0.215 Pascal --> 0.215 Pascal No Conversion Required
Density of Gas: 0.00128 Kilogram per Cubic Meter --> 0.00128 Kilogram per Cubic Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

C_RMS = sqrt((3*P_gas)/ρ_gas) --> sqrt((3*0.215)/0.00128)

Evaluating ... ...

C_RMS = 22.447856245085

STEP 3: Convert Result to Output's Unit

22.447856245085 Meter per Second --> No Conversion Required

FINAL ANSWER

22.447856245085 ≈ 22.44786 Meter per Second <-- Root Mean Square Speed

What are the postulates of kinetic theory of gases?

1) Actual volume of gas molecules is negligible in comparison to the total volume of the gas. 2) no force of attraction between the gas molecules. 3) Particles of gas are in constant random motion. 4) Particles of gas collide with each other and with the walls of the container. 5)Collisions are perfectly elastic. 6) Different particles of the gas, have different speeds. 7) The average kinetic energy of the gas molecule is directly proportional to the absolute temperature.
