if a glass of water fully filled is freezed in a freezer then why does'nt the volume decreases?

Question

we know that in liq. the molecules r at a larger distanse than that of asolid; on freezing it should be close to each other then why doesn't it appears to us

Answer 1

OK fast explanation...it has to do with Water's "density maximum"...as the water starts to freeze, the water molecules start to arrange into their ice like structure (going from liquid to solid)..this cause some open air spots to occur, which causes more volume (ice and open air areas)...

Answer 2

The Thermal Mechanics in contact are .... Water starts to strengthen whilst it reaches 4°C on cooling. because it comes right down to freezing factor, (0°C) it has decreased in Density and greater advantageous in quantity via approximately 8% of its unique quantity. If the bottle is thoroughly filled (no air area), this enlargement of the liquid produces an awesome Hydraulic stress interior the bottle which could not stand up to its stress performing on the indoors area of the glass. The bottle will shatter yet, because of the fact the liquid is now frozen good, it can not be observed till faraway from the freezer and the water starts to soften and run out. (it is the familiar reason for burst water pipes in wintry climate whilst a water line is thoroughly finished and remoted at the two ends).

Answer 3

The reason why water expands is because of its molecular structure.

Water in its liquid state will have it molecules (H2O) moving freely. When its temperature decreases these molecules will experience a drop in temperature and thus also a drop in its kinetic energy meaning that its molecules do not move as freely as before making its volume smaller. This is at around 4deg.

Now, when the water freezes, due to the water molecule's bipolar state, these molecules will start to form into ice crystals (imagine a snow flake) and thus have "spaces" between the crystalline H2O molecules. This acccounts for the expansion in volume.

This does not happen to other liquids, say oil, because it is a non polar compound and does not form into crystals when it freezes.

Answer 4

Volume of water increases as it freeze. If you freeze a fully filled glass if you look closer you can see a small hump on the top of the glass. Since there is no space to expand from the sides, the ice is pushed up when water freeze.

Answer 5

Water is one of the only compounds the expands when frozen. This is cause by air molecules getting in between the water molecules of the mass of ice. The air inside is what makes ice float.

Answer 6

Usually when ever you freeze something, the volume increases. That is why you don't want to keep cans of soda in the freezer -- they will explode!

Answer 7

No, in a liquid form, molecules are closer together than at in solid form. Also, ice forms a crystaline structure that uses up much more space than a liquid does.

Answer 8

Water is one of those odd liquids that are actually at their densest (most compact) at 4ºC, right before freezing. As water freezes, it actually expands, causing much misery for water pipes in freezing climates.

Answer 9

Becz volume of ice is greater than water

Answer 10

They actually increase. That's why you should never leave a unopened bottle or can in the freezer. It'll explode.
