When the molecules are cold they lose energy and come closer together(contracting) and when they are hot they gain energy and move further apart(expanding). An excellent example is water. When molecules are hot they speed up and move around a lot faster. When they are cool they move much slower.

∙ 13y agoThe molecule tend to move faster in hot objects rather than cold ones. The reason being that the heat makes the warmer object move faster and the colder to stay closer together. That is why an ice cube is solid and a peice of cheese is melted. Because if you make somthing cold it will usually freeze and if you warm somthing it will usually melt.

∙ 13y agowhen molecules are cold they start to freeze up and come closer together as if you were in a group in a blizzare you would want to get body warmth

∙ 14y agoheated molecules will vibrate more than a colder one because it has more energy
Wiki User
∙ 13y agoWhen molecules have more heat energy given to them (hotter) they move around more and are thus further apart.

What happens to the molecules when a solid is melted?
Nothing happens to the molecules. They're just warmer and moving around faster.
What happens when sucrose is dissolved in water?
The sugar molecules disperse themselves between the water-molecules, making it seem as though they disappear, 'hidden' by the water molecules. It is important to know if the dissolving water is hot, lukewarm or cold. This affects the rate at which the solute mixes with the solvent.
What happens to water molecules as water evaporates?
The hydrogen bonds between the water molecules in the liquid are broken.
What happens to water molecules when they are stirred?
They move.
What happens to the molecules in a balloon when they are heated?
they pop
What happens to the water molecules when the air above gets cold?
the water molecules get cold and expand and turn into ice
What happens to the molecules of air when they are heated?
they get exited and move faster than cold molecules
When you beathe on cold window what happens?
the water molecules in your breath condenses as moisture on the glass.
What happens to the molecules when a material is heated up or cooled down?
Molecules heat up or cool down. like when you rub your hands together you get warmer and when you go out in the cold you get cold quickly.
What happens when you put a balloon in cold water?
The balloon shrinks because the molecules are moving slower
What happens to the sugar when it dissolves into cold water?
the sugar particles gets adjusted between the spaces of water molecules.
What motion do molecules move when in cold water?
does molecules move in cold water
What do molecules do to make it cold?
When it is cold, molecules move slower than when it is hot.
Which of these events happens first in Earth's polar regions A Denser water sinks B Water travels as a deep current C Water molecules move closer together D Cold air chills water molecules?
In polar regions of Earth, FIRST, cold air chills the water molecules.
Are molecules in hot water different then molecules in cold water?
If you have the same volume of both then there are in cold water more molecules.
How do you think molecules move in hot and in cold air?
In hot areas the molecules move quickly and in cold areas the molecules move slower.
How do you think the molecules move in hot and cold air?
In hot areas the molecules move quickly and in cold areas the molecules move slower.
