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.

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 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.
Why doesn't cold air takes up space?
Cold air does take up space. All matter does.Cold air just takes up less space than warm air.
Why steam takes up more space than liquid water?

Do 6 billion grains take up more or less space than you expected?
Less space than I expected.
Cold air has more molecules occupying a cubic centimeter of space then warm air therefore it has a what pressure?
Cold air has more molecules occupying space than warm air, therefore it has high pressure.
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 does a kilogram of sand take up less space than a kilogram of feathers?
because sand is smaller than feathers and it would take up as much space with the sand , and if the feathers were there it would take up more space because its and larger object than the sand .
Why does 1 kg of foam take up more space than 1 kg of rock?

Is this sentence grammatically correct - A horse's teeth takes up more space than its brain?
No. It should be: A horse's teeth take up more space than it's brain.
Why is cold oil more dense than hot oil?
Cold oil is more dense than hot oil because the molecules are closer together at lower temperatures, making the oil more compact and occupying less space. When oil is heated, the molecules have more thermal energy and move around more freely, causing them to spread out and occupy more space, which results in lower density.
Does a cup of raisin take up more space than a cup of ceral?
