Critical Temperature without use of Van der Waals Constant Solution

STEP 0: Pre-Calculation Summary
Formula Used
Critical Temperature = (8/3)*((Critical Pressure*Critical Volume)/[R])
Tc = (8/3)*((Pc*Vcr)/[R])
This formula uses 1 Constants, 3 Variables
Constants Used
[R] - Universal gas constant Value Taken As 8.31446261815324
Variables Used
Critical Temperature - (Measured in Kelvin) - Critical Temperature is the highest temperature at which the substance can exist as a liquid. At this phase boundaries vanish, and the substance can exist both as a liquid and vapor.
Critical Pressure - (Measured in Pascal) - Critical Pressure is the minimum pressure required to liquify a substance at the critical temperature.
Critical Volume - (Measured in Cubic Meter) - The Critical Volume is the volume occupied by the unit mass of gas at critical temperature and pressure.
STEP 1: Convert Input(s) to Base Unit
Critical Pressure: 218 Pascal --> 218 Pascal No Conversion Required
Critical Volume: 5 Liter --> 0.005 Cubic Meter (Check conversion ​here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Tc = (8/3)*((Pc*Vcr)/[R]) --> (8/3)*((218*0.005)/[R])
Evaluating ... ...
Tc = 0.34959164532419
STEP 3: Convert Result to Output's Unit
0.34959164532419 Kelvin --> No Conversion Required
FINAL ANSWER
0.34959164532419 0.349592 Kelvin <-- Critical Temperature

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.
