Does Heating a Balloon Affect its Surface Energy?

AI Thread Summary
Heating the air inside a balloon at constant pressure raises the temperature, which can affect the balloon's properties. The discussion centers on whether the balloon has surface energy and its origin, with some suggesting it relates to the elastic forces of the stretched material. As the balloon expands due to heating, there is a belief that surface energy increases with surface area. However, a counterpoint is made that there is no change in surface energy despite the increase in temperature and surface area. The conversation seeks clarification from experts on the relationship between heating, surface energy, and balloon elasticity.

Homework Statement


What will happen to the surface energy of a balloon when the air inside it is heated at a constant pressure?


The Attempt at a Solution



I don't understand how will a balloon have surface energy. What is its origin? Is it due to the elastic forces of the stretched balloon?
If yes then the surface energy increases as its surface area increases on heating.
Any ideas appreciated.

Yes, it has to be that way. Imagine the surface as a net. Each molecule acts as a micro-spring (a connection of the net).
If yes then the surface energy increases as its surface area increases on heating.

Right
Any ideas appreciated.
 
You are wrong. There is no change is surface energy (as per the answer). This was the doubt that made me post this question. Experts please reply.
 

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...
