AI Thread Summary
The discussion revolves around calculating the work done during the expansion of air in a closed piston cylinder, where the process follows the equation PV^1.2 = constant. Participants clarify that this represents an adiabatic process, indicating no heat transfer occurs. The work done can be calculated using the formula W = -P(Vf - Vi), but the unique exponent of 1.2 raises questions about its implications. There is a request for further explanation on handling the V^1.2 relationship in the context of the work calculation. Overall, the thread seeks assistance in understanding the specific characteristics of this adiabatic process and the associated calculations.

hey guys got this question that i have been stuck on for a while.

air is expanded from 1M Pa at 327 degrees celcius to 200kPa in a closed piston cylinder device. for the process PV^1.2 = constant. calculate the work done during this process

any help will be welcomed

cheers

temperature constant? work done= -pV ?
 
if [P(V^1.2) = constant] this is an adibatic process which means that there is no heat added or taken away.
 
I have not encountered something like V^1.2 before. Is that right? If so can someone enlighten me about it?
 

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...

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 .
