Calculate Work of Expansion in Chemical Reaction | 100 cm2 Container

AI Thread Summary
To calculate the work of expansion in a chemical reaction occurring in a 100 cm2 container with a piston, the relevant equation is W = ∫ p dv, where the limits should be set as V1 and V2. The piston moves out by 10 cm against an external pressure of 101.3 kPa. The work done by the system can be calculated using the formula W = PΔV, where ΔV is the change in volume. Participants confirm the correct approach and emphasize the importance of using the appropriate limits for volume in the integration. This method allows for accurate calculation of the work of expansion in the given scenario.

Homework Statement



A chemical reaction takes place in a container of cross-sectional area 100 cm2. The container has a loosely fitting piston at one end. As a result of the reaction, then piston is pushed out by 10 cm against an external pressure of 101.3 kPa. Calculate the work of expansion done by the system.

I really don't know what equation to be using?
 
Physics news on Phys.org
is it

W = \int^v_v p dv
 
Yes, that's the one. Except the limits should probably be "V1" and "V2".
 

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...
