So, I was drinking from my flask. I put ice water inside. (Basically some ice cubes and water)
If the flask is scientifically tested that it drops by 1°c per 16 hours. Wouldn’t the water level rise in the flask as the ice melts? But since it is a vacuum flask, it would hold the water in and prevent it from overflowing. (Rubber cap with tight insulation)
So, if the ice melts and the water level can’t increase wouldn’t the ice cube not melt and remain ice forever?
In: Physics
Water that freezes expands that that is why if float in water, the density is lower.
So ice that melt will decrease in volume so the water will take up less space then the ice did. If you would fill a bottle with liquid water and put it in the freezer so it turns into ice the volume will expand. The result is either that the rubber cap leaks or is force out so water can escape that way or the water example in the bottle and it gets deformed and might crack because the pressure will increase.
A vacuum flask will not have a content 1°c drop per 16 hours the rat the temperature change will depend on the temperature difference between the outside and inside. It is also not a drop in general but a move towards the outside temperature
So that rate might be what happens as a specific inside and outside temperature but at different temperatures is will not be the same.
