Do the properties of ice change relative to the temperature of the water used to make it?


I’ve always just assumed that the only thing that would change is how long it takes to become ice. Am I correct?

The vibration of the molecules will slow down the colder it gets, so thats really the only thing that changes. Density doesn’t change as the distance between particles is the same no matter how fast the particles are vibrating. But vapor pressure may decrease as all things including solids have vapor pressure that are very negligible, but still vapor pressure of the ice will decrease as it cools.

Nothing much as far as i know changes other then those two things.

There is a difference in dissolved substances. If you start with boiled water, you decrease the amount of dissolving gas in your water, and if you cool it quickly enough, there won’t be much chance for it to redissolve. This might get you clearer ice.

On the flip side, if your water is dirty, and has dissolved solids in it, then starting with cold water would give you the chance to separate them from the water, because solids don’t dissolve well in cold water.

Other than that though, I can’t think of any inherent difference between them.

it does change the end product because freezing time matters to crystal formation.

when objects freeze, they begin to solidify is multiple independent locations. if the substance freezing is a regular crystal structure (ice), these regions called “grains” will follow their crystalline pattern until they bump into each other. the points where they meet are called “grain boundaries” and the molecules can’t join in the normal way.

grain size impacts a number of physical qualities. in ice, the part we tend to care about is appearance. grain boundaries disrupt light. freezing more slowly increases grain size and allow for more clear ice. which is why clear ice gadgets are actually insulated. slower freezing, bigger crystals, clearer ice.
