Any molecule will speed up it's movement as it gets hotter. Ice is water in a cold state where the molecules are barely moving so it is in it's "solid" state. When it warms up, the molecules start moving a little faster and it goes into it's "liquid" state. As it heats up more the molecules are moving so fast that they can separate from the rest of the group and go into it's "gas" state. This is true with any element or molecule, the only difference is that each one has their own specific temperatures where these changes occur.

Sound waves travel faster in water than in air because the molecules are in close contact and exert forces on each other (like a spring) when compressed together.

∙ 14y agoYes...the hotter something is the faster the molecules move.
Wiki User
∙ 12y agoOn the contrary: the molecules loose energy when they freeze so the molecules attract more each other, so they don't move.
Molecules only move when they are in liquid or gas state :)

Why does the soot particles move faster in warm water than in cold water?
The water molecules in warm water have greater kinetic energy, making them move faster.
Why do substance dissolve faster in warm water?
The warmth make the molecules of some substances move faster.
Why does water expand at the equator?
Water expands at the equator because it is warm there, and warm molecules expand. Warm molecules expand and cold molecules decrease in size.
What does food coloring mix into the fastest hot warm or cold water?
Warm Water! when molecules inside of an object heat up, the molecules go faster! which will absorbe the food coloring faster.
What makes salt dissolve faster hot or cold water?
Hot waterWhen substances have a high temperature, they have more energy. The more energy molecules have, the faster they move. The molecules in hot water move faster than cold water because of the higher energy. Because the molecules of hot water move faster, they can more easily break apart other molecules of a different substance when they come into contact. The fast moving water molecules can break apart the bonds between the salt crystals so they become dissolved into the water.
How do ice water molecules differ from warm water molecules?
The main difference is that ice water molecules have very low kinetic energy, i.e. they don't move very fast, compared to warm water molecules. The other difference is in the intermolecular forces holding the molecules together. They are greater in ice than in warm water.
Why does the soot particles move faster in warm water than in cold water?
The water molecules in warm water have greater kinetic energy, making them move faster.
How does warm air molecules move?
The molecules in warm air move faster
Why do substance dissolve faster in warm water?
The warmth make the molecules of some substances move faster.
Why does water expand at the equator?
Water expands at the equator because it is warm there, and warm molecules expand. Warm molecules expand and cold molecules decrease in size.
Do Jelly babies dissolve in cold or warm water faster?
warm water because at a higher temperature the water molecules have more energy and can move faster therefore they are able to break down the molecules in the jelly babies quicker than in cold water
What does food coloring mix into the fastest hot warm or cold water?
Warm Water! when molecules inside of an object heat up, the molecules go faster! which will absorbe the food coloring faster.
Why do antacids dissolve faster in warm water?
It has more energy in the form of water molecules that vibrate and move around faster than those in cold water.
Why is warm water warm and cold water cold?
Warm water is warm because the molcules heat up and make friction they move around much faster when an object is a liquid then a solid. Cold water is in the process of becoming a solid the molecules will slow down and compact to compact molecules need coldness and when something is warming up it is melting and needs heat to melt. duh.
What is the difference in water molecules in warm water and cold water?
The molecules in warm water are moving quicker, meaning that the hydrogen bonds between the molecules are breaking very quickly whereas the molecules in cold water are moving much slower.
How fast do gases move?
The gases only move fast when they are warm, and they are followed by liquid to make them move fast. They move the slowest when they are followed by solids, and when they are cool.
Do most solutes dissolve better in warm water or in cold water?
Most solutes dissolve better in warm water because the molecules of warm water move faster, so the water molecules and the solute come in contact more often. For solid solutes, it is generally true that you can dissolve more in warm water than cold water (though I'm not sure the above answer states the reason for this correctly). But gasses generally dissolve better in cold water.
