Molecules move faster when hot water then in cold. Temperature is a measure of the average kinetic energy of the atoms. Molecules move faster in hot water because the heat is giving the molecules more energy. Molecules move slower in cold water because heat has/gives energy and when something is cold it has very little heat. So there is very little energy. So there is very little movement.
I have a science quiz tommorrow, and this was VERY helpful. :D

∙ 15y agoThe steam moves quicker because there are less interactions between the water molecules themselves. In the liquid state they are in closer proximity so van der waals interactions slow them down and draw the molecules together.

Wiki User
∙ 12y agoThe molecules in hot water move faster because they have more energy. Heat is a form of energy.
Wiki User
∙ 12y agoIf under all the same conditions, the water with more heat, therefore more energy, will move faster.
Also, a gaseous form will in general move more quickly than its condensed form.

What motion do molecules move when in cold water?
does molecules move in cold water
Why does salt take longer to melt in cold water?
because cold water molecules move slower at colder temperature.
Why do molecules in hot water move faster than in cold water?
Temperature is a measure of molecular motion. Fast molecules are hot. Molecules that move slowly can always be "heated" and then they will move faster and thus will be hot.
Why does not sugar dissolve in cold milk?
Even in cold water sugar will dissolve eventually, but it does dissolve faster in hot water. Hot water molecules move faster than cold water molecules and therefore can more easily break sugar molecules out of solid sugar and into solution.
What happens to water molecules when they are heated?
Like all molecules, a molecule of H20 is in constant motion; 'hot' molecules move faster than 'cold' molecules. If the molecules move slowly enough the substance appears stationary to us (frozen water) and if they move quickly enough they will expand to fill their container (vapor or gas water.)
What motion do molecules move when in cold water?
does molecules move in cold water
Do hot and cold water molecules move at the same speed?
Hot water molecules move a lot faster han cold water molecules because they have a higher kinetic energy due to the heat.
Why does salt take longer to melt in cold water?
because cold water molecules move slower at colder temperature.
Why do molecules in hot water move faster than in cold water?
Temperature is a measure of molecular motion. Fast molecules are hot. Molecules that move slowly can always be "heated" and then they will move faster and thus will be hot.
What are the differences in the way water molecules move in cold room temperature and in hot water?
Water molecules have more space between each other in cold room temperature than hot water.
What happened to the molecules of water if you add snow into it?
They will move slower because they will get cold.
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.
Do molecules in water move slower in cold water?
Yes, the less heat there is present, the less heat, the slower the molecules will move. This is due to a lack of energy given from the heat.
Why does not sugar dissolve in cold milk?
Even in cold water sugar will dissolve eventually, but it does dissolve faster in hot water. Hot water molecules move faster than cold water molecules and therefore can more easily break sugar molecules out of solid sugar and into solution.

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.
