Does Heating a Pop Can Increase Internal Pressure?

AI Thread Summary
Heating a pop can with the tab removed increases the internal pressure due to the ideal gas law, which states that pressure rises with temperature if the volume remains constant. As the can heats up, the air inside expands, leading to higher pressure compared to the cooler air outside. If the external pressure exceeds the internal pressure, air will flow into the can until equilibrium is reached. The rate of temperature increase inside the can depends on the heat transfer efficiency, which can vary based on the can's material and the surrounding environment. Ultimately, heating the can results in a dynamic balance between internal and external pressures.

Say there's a pop can with the tab already removed. If the can was heated up, would there be more pressure inside or outside the can? Please explain thoroughly and with a lot of detail.

My attempt: I'm guessing there will be more pressure outside but not sure why? I'm guessing b/c the temperature in the room is cooler and the pressure escapes from the can, please explain not really sure
Please help asap, need it for homework (8

If the pressure outside is greater than the pressure inside, wouldn't air flow from outside to inside, since the can is open ?
 
Air outside and inside start at equilibrium.
Can gets heated up.
How fast does the temperature of the air volume inside of the can rise?
How fast does the temperature of the air volume outside of the can rise?

If one rises faster than the other, what happens to the air? Which way does it flow?
 

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...
