What Are the Van der Waals Constants for Sulfur Hexafluoride (SF6)?

AI Thread Summary
The van der Waals constants for Sulfur Hexafluoride (SF6) are a = 6.871 L² bar/mol² and b = 0.0562 L/mol. The critical temperature (Tc) is 318.7 K and the critical pressure (Pc) is 37.6 bar. These constants are essential for understanding the intermolecular forces within SF6 and are used in the van der Waals equation to analyze gas behavior under varying conditions. The information is crucial for drawing critical points and isothermal curves in laboratory settings. Accurate values for these constants facilitate better predictions of gas behavior at high pressures and low temperatures.

Could anyone here say me what's the constants of van der waals for the Sulfur Hexaflouride (SF6)
 
Physics news on Phys.org
please anyone can help me? it is so urgent since this is for draw the critical point and the critical isothermal for the laboratory. Or you can say me what's the critical molar volume or the critical volume for this gas, because I have the critical pressure and temperature.
 


The van der Waals constants for Sulfur Hexafluoride (SF6) are as follows:

a = 6.871 L^2 bar/mol^2
b = 0.0562 L/mol
Tc = 318.7 K
Pc = 37.6 bar

These constants describe the intermolecular forces between SF6 molecules, and are used in the van der Waals equation to calculate the behavior of gases at high pressures and low temperatures.

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Struggling to make relation between elastic force and height'

Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...
