what happens to a glass of water when you freeze it?

I'd check out the Billy Nye the science guy website... see if you can get a good answer there.\n\nAnd I'd tell your child that they need to start on their reports a little sooner than the day before next time... but you probably already know that...

it doesnt, however the energy is lost faster in hot water than in cooler water.  The rate at which all water freezes is the same.

Ice lowers the melting point of water, so it causes the ice to turn to liquid water and break up.  If it's *really* cold, this doesn't help.

So anti-freeze and salt causes a freezing point depression in the water which means as you add solvent such as salt the freezing point is lowered (hence when you add salt to your windshield the ice melts).  There is a simple mathematic equation that will relate the change of Temp freezing to the amout of solvent added.  (ΔTf = Kfcm).  Kf is the freezing point constant of the solvent and cm is the molal concentration of the solvent. So as you can see from the equation the ΔTf will be greater as you increase cm so the effects of adding a solvent will depend on how much solvent you add.  \n\nSo a simple experiment would be to add increasing amounts of salt and antifreeze to constant volumes of water and determine the freezing temperatures of each one.  You should also want to calculate the molal concentration of each one and try to determine before hand what the freezing points should be (hypothesis).

All water freezes at some temperature. However, pure water can be supercooled below its freezing point if you don't give the ice anything to nucleate around. It will then homogeneously freeze (to very clear ice) below a certain temperature though.

yea it is that glass that looks whitish, it looks like if you put a normal glass in the freezer :)

Water expands when it freezes. The drink was mostly water. That broke the glass, but it brokr before the drink was completely frozen, so the carbonation caused the drink to spray all over the freezer.

Water is one of the few substances that expands as it freezes.  From 4 degrees Celsius down to 0 degrees water expands and as a result the frozen solid form is less dense than the liquid form and that is why ice floats.\nThe water in the soft drink expands and the can cannot hold the increase in volume.

In freezing, the latent heat of fusion in the water molecules is released with out the water changing its temperature. The molecules lose average kinetic energy, and start behaving like particles in a solid, with minimal vibrational movements and close seperations. The reverse process is melting, where latent heat of fusion is absorbed by the water molecules, increasing average kinetic energy which is used to break bonds between molecules so they start behaving like particles in a fluid.\n\nThe transition from liquid to vapour, and vice versa follows a similar path, except the heat energy required for the process is in this case called latent heat of vaporisation.

When you have water in a glass its liquid.\n You freeze it it becomes a solid - But its still water. \nYou take that ice cube and heat it in a pan it becomes steam - But its still water.\nSo you have three forms of the same water each with its own properties and function but still each is water.\nYou have God the Father, God the Son, God the Holy Spirit. All three are still God but just like the water each has different properties and functions.

Any closed container of liquid will explode if left in the freezer too long. The liqued will expand, increasing pressure on the container until it rips open spreading liqid over everything

This is what happens if you start freezing a glass of sea water: it will start to freeze at a lower temperature than fresh water (around -4 C, but variable depending on the salinity you start with). \nImportant, the salinity of the ice formed is almost pure water (it is not salty). Some salty water may be trapped on the ice though, but the ice itself is fresh water. If you keep lowering the temperature, more ice will form and the remaining salty water gets even saltier. This process will continues until an eutectic is reached and then you will have a fast crystallization of ice, a mineral called hydrohalite. This eutectic is about -21 C, but depends on other components, like Mg, Ca that are also abundant in the composition of sea water.

when you pour water on the ice, the ice has layer of water around it, but its still really cold. when the new water stays next to it, the ice cube freezes the water around it, if two ice cubes are touching, they will freeze the water between them and stick to eachother

yes you can freeze a water balloon

It DOESN'T! The ice makes room for itself when the glass fills with water. Melted ice takes up less room that solid. So when it melts, the volume in the glass is the same.

Under normal curcumstances when water is cooled, it will form ice at its freezing point.  That is crystallisation takes place and an ice cube is formed.  If now the liquid is cooled past its freezing point without crystallisation taking place, a glassy substance is formed.\n\nWe can also cool saturated solution, without crystalllisation taking place to form a super saturated solution.  This is super cooling.

depends on the ice...\n\nmany different types of ice in different states of being 'frozen' and at different temperatures and with\ndifferent degrees of purity of the water or other frozen substance...\n\nthe answer would be yes more often than no...
