Is cold water smaler than warm water in volume?

Question

If yes, do you maybe know what the difference in volume is?

Answer 1

Water contracts as it gets cooler until it reaches 4 degrees Celsius. If you get colder than that the water expands. Water also expands when it freezes.

http://en.wikipedia.org/wiki/Water#Water.27s_freezing_point_anomaly

Here are some specific figures on water density at various temperatures:
http://www.simetric.co.uk/si_water.htm

and here are two specific figures:
Density at 4 degrees Celsius = 1.0000
Density at 80 degrees Celsius = 0..9718

So water is about 3% less dense at 80 than it is at 4.

Answer 2

Yes, up to a point just slightly above freezing. Cold water is more dense than hot water, easily proved by filling a bottle with water and putting it in the refrigerator. It will change the shape of the bottle, and when you open it, there will be airspace introduced into the bottle, proving the volume to be less.

However, if you put the same bottle in the freezer, it will expand, and very possibly rupture the bottle! Ice is less dense than water, even cold water, which is easily proved by the fact that it floats in water.

Answer 3

When you heat up water, the water molecules start moving around faster and faster. They bounce off each other and move farther apart. Because there's more space between the molecules, a volume of hot water has fewer molecules in it and weighs a little bit less than the same volume of cold water. So hot water is less dense than cold water.

Answer 4

Yes, it is. Water at about 4 dgrees C is most dense having a defined density of 1.0000 g/cm3

Density decreases as the water warms up by about 0.0002 g/cm3 per degree, or at least thats is the factor we use in the lab to adjust the specific gravity of water based on its temperature.

The presence of anything dissolved or suspended in the water can greatly affect its density.

Answer 5

Pure water hits its maximum density at about 37 degrees F. This is why cold water sinks, and hot water rises, but ice floats.

Answer 6

Density of cold water is higher than warm water...

SO for same weight, it may be have small volume

Answer 7

cold water has MORE volume than hot water. very wierd hey. thats why ice floats, cause it is less dense than normal water, therefor colder is more volume because the perticals are seperated further

Answer 8

at 40 degrees F, water attains it's maximum density

Answer 9

How cold? otherwise no

Answer 10

no
