If you have the same volume of both then there are in cold water more molecules.

Why does warm water rise and cold water sink?
Actually you are wrong, its vise versa, hot water rises and cold water sinks. This is because when water molecules gain energy, they become hot. Molecules try to move away from one another. And this leads to reduction in density. Since density of water reduces as it becomes hot, how water moves up and cold water sinks down.
Is hot water less dense than cold water?
Yes, because the higher the temperature, the faster and more spread out the molecules, therefore making hot water less dense than cold water.
Why the gases are more soluble in cold water than they are in hot water?
gas is more soluble in cold water. In hot water, the molecules are farther apart, leaving room for gas to escape. That's why it's LESS soluble, and why hot water makes clearer ice cubes. Cold water molecules are close together, trapping in the gas and dissolving it. We keep pop in the freezer so the carbonation will last longer.
Does hot water or cold water particles move faster?
hot water molecules move faster with food coloring.you can experiment it with the help of following steps:-Fill the glasses with the same amount of water, one cold and one hot.Put one drop of food coloring into both glasses as quickly as possible.Watch what happens to the food coloring.If you watch closely you will notice that the food coloring spreads faster throughout the hot water than in the cold. The molecules in the hot water move at a faster rate, spreading the food coloring faster than the cold water molecules which mover
Does boiling water have oxygen in it?
No,boiling water does not have oxygen . Cold water molecules move slowly meaning there is space between the molecules for more oxygen to dissolve. Hot water molecules move rapidly meaning the space between the water molecules is less avalible for the oxygen molecues to dissolve into.
Which are faster cold water molecules or hot water molecules?
Of course, hot water molecules, having more kinetic energy.
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 are water molecules more likely to escape from hot water then cold?
Hot water means the water molecules has attained energy from the temperature applied and hence their kinetic energy increases. Thus movement is possible for water molecules in hot water than cold water.
How are the water molecules positioned in the hot cup?
The molecules in a cup of hot water are spaced farther away from eachother than the molecules in a cold cup of water.
Why do raisins plump up more quickly in hot water than in cold water?
Raisins plump up more quickly in hot water because the molecules in hot water move quicker than molecules in cold water so the hot water molecules diffuse quicker into the raisin.
Does cold water drain faster than hot water?
no hot water will drip faster than cold water.This is because the molecules in hot water move around faster than in cold water. This makes it easier for molecules in hot water to slip right past other
Why does hot water float above cold?
In hot water the molecules vibrate faster than cold, resulting in the same number of molecules taking up a larger space. This means that hot water is less dense than cold water, and thus floats above the cold water.
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.
Who is better to dissolve in hot water or cold water?
hot water because the molecules are moving faster
Why does cold water have more molecules than hot water?
You may want to frame this question in this manner, "Why does cubic unit of cold water have more molecules than same cubic unit of hot water" This is so because heat causes movement in molecules and malkes them move apart. Hence the hotter the water, the further apart the molecules. Therefore, cold water has more molecules than hot water of same unit.
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.
Does salt dissolve better in hot or cold?
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.
