Freezing water in an unexpandable container?

AI Thread Summary
If a strong, unexpandable container is filled completely with water and subjected to freezing, the water would freeze under immense pressure, maintaining its volume. This pressure could lead to the formation of different types of ice, as there are multiple phases of ice that depend on temperature and pressure conditions. The freezing point of water would likely decrease under such conditions, although the exact amount is uncertain. The discussion highlights the complex nature of water's phase diagram and the various forms ice can take under different pressures. Overall, the scenario poses intriguing questions about the physical properties of water and ice.

If you did had a container that was strong enough to resist the expansive forces generated as the water in it freezes, what would happen? (assuming the container is filled completely with water)

Thanks for any answers in advance, and I hope this post is in the correct place, if not, then sorry!

Welcome to Physics Forums leakeg!

If the container really is strong enough, the frozen water would be under a tremendous amount of pressure in order to maintain its original volume.
 
thanks for your reply!

so you're saying the water would freeze? so we would have a compressed solid? or would the ice be a different form of ice? would it freeze at a colder temperature?

is this even possible in the real world?

wow that was a lot of questions haha.
 
There is something like 7 different types of water ice (the phase diagram of water ice is VERY complicated), which form it freezes into would depend on the temperature and pressure.
 
alright, cheers!

how much do you guys think it would lower the freezing point by?
 

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?

Thread 'Beam on an inclined plane'

Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
