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.
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
