How Much Work Does a Non-Ideal Gas Perform During Expansion?

AI Thread Summary
The discussion centers on calculating the work done by a non-ideal monatomic gas during expansion from an initial volume of 0.3 m³ to a final volume of 0.44 m³ at a constant temperature of 100 K. The pressure-volume relationship is given as P = Po(Vo/V)^(1/2), with specific values for Po and Vo provided. Participants are encouraged to consider the definition of work done by a gas, which remains applicable even for non-ideal gases. The conversation highlights the need for understanding the principles behind gas behavior to solve the problem effectively. Overall, the focus is on applying theoretical concepts to practical calculations involving non-ideal gas behavior.

Homework Statement



For some particular unusual non-ideal monatomic gas, take the relation beween P and V at some fixed To to be
P = Po(Vo/V)1/2.
Let To = 100 K, Po = 100000 Pa, and Vo = 0.1 m3.

Homework Equations



How much work does this gas do if it expands, pushing on a piston, from Vi = 0.3 m3 to Vf = 0.44 m3 at T = 100 K?

The Attempt at a Solution



Someone please help?
I don't understand non-ideal gases.

Even though you don't know much about non-ideal gases, that doesn't mean you can't do anything here. Give me some of your thoughts on the problem. Here's a hint to get you started thinking:

What is the definition of work done by a gas? This should still apply to this non-ideal gas, correct?
 

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...
