Objects expand when heated because the heat 'gives' molecules more energy, so they move around more. This vibration, as molecules are pushed further apart, is manifested as a larger volume.
An exception is water, which contracts as it cools until you reach about 3.98 ° C then starts to expand as it cools more. This is caused by the shape of water molecules.
Then again, there is Zirconium Tungstate which contracts as it is heated up to 800o C (an effect caused by lattice formation that twists and turns individual molecules).

Do hot water take up more space than cold water?
Yes until it turns to ice when it take sup more space than hot water.
Why does steam take up more space than liquid water?
why does steam take up more space than liquid water
When water freezes does it take up more space or less space?
The water will expand on freezing, so taking up more space.
Why warm water is heavy than cold water?
Warm water is not heavier than cold water. Warm water is lighter than cold water because water, like most other materials, expands when heated causing it to take up more space while weighing the same amount (it becomes less dense).
Why steam takes up more space than liquid water?
why does steam take up more space than liquid water
Why does water take up more space as steam then it does as liquid water?
Sort of, as steam water spreads around more so you could say that water takes up more space as steam.
Does cold air take up more space than hot air?
No, hot air takes up more space than cold air. When matter is heated, it expands, when it is chilled, it contracts (water is an exception, as ice crystals expand from liquid water). To prove this, take an empty water bottle and shove it in the freezer for an hour or so. When taken out, the air inside the bottle will be cold. If you wrap a balloon around the bottle's opening, you will trap the cold air inside the bottle. Now, pour some hot water over the bottle, heating it, and the air inside (be careful). As the air warms, it will expand, and therefore take up more room. Since the bottle is a confined space, the balloon over the bottle's mouth will inflate slightly to give somewhere for the expanded air to go.
What happens when you take medicine with cold water?
there well if u gona take medicine inside nothing will happened but if u have some dissolving calcium tablets in water and if u put it into cold water it will dissolve but it will take more time then the normal water but if u take medicine with cold water the water will be warm in mints so don't worry :)
Which do you think is more denser warm water or cold water?
Cold water is more dense than warm water. As a group of water molecules lose energy (lose heat), they move slower and slower in three-dimensional space. Since the individual water molecules are moving more slowly, there is a greater opportunity for hydrogen bonds to form and be retained between individual water molecules. Since there are a greater degree of intermolecular bonding take place, the molecules are packed more closely together, and are thus more dense.
How do astronauts get there basic needs in space food water and more?
They have to take basic necessities in space. Food water and other things are carried from earth only.
Why does hot air take up more space than cold air?
When energy (in this case, heat) is added, it excites the molecules and causes them to begin to move more. This extra movement causes them to repel one another more, causing the substance to take up more space.
How long does brown sugar take to dissolve in cold water?
That depends on the relative quantities of sugar and water, the water temperature (more definitely than merely "cold"), and any agitation (stirring).
