I just started thermodynamics and I can get the concepts its just application that's a bit hard. It makes sense that most objects will expand when you heat them up. I'm not sure this is the exact reason, but is it because the particles gain more energy to move around faster and repel each other more?
Also there are few cases of expansion which I can't understand (without experiment)
1. A liquid L in a closed container C with 2 different conductivities.
If [tex] \kappa_L = 0[/tex] but the container expands, what will happen to the liquid?
If [tex] \kappa_C = 0[/tex] but the liquid expands, will it break the container?
2. This is quite similar, but suppose it's now a glass of beer :)
Both have different non-zero conductivities, but is there a way to find how much beer spills over, or how much more volume is made available (due to expanding glass)
3. I think I asked this before but it still doesn't make sense. A rectangular plate with a circular hole heats up and expands... what happens to the hole?
Apparently it will decrease, but I'm thinking it will get bigger because the whole plate would just scale up and expand in all directions ??
(just a quick question on TD equilibrium: a 5°C in a 25° room will warm up to 25°C at equilibrium?)
Thanks
