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.
What else can I help you with?
Is cold water more or less dense than warm water?
cold ocean waer has more dense than warm water.
How are the water molecules positioned in the hot cup?
In a hot cup of water, the water molecules have higher kinetic energy and are moving faster than in a cold cup. This results in the water molecules being more spread out and having increased motion, leading to a less structured arrangement compared to cold water.
Does hot water or cold water evaporate faster?
Hot water freezes faster than cold water. Water molecules are composed of one oxygen atom bonded to two hydrogen molecules. When water molecules come in close contact, a natural repulsion between the molecules to stretch and store energy. As the water heats, the hydrogen bonds stretch as the water gets less dense and the molecules move further apart.
What are the differences in the way water molecules move in cold room temperature and in hot water?
In cold room temperature, water molecules move slower and are closer together due to lower kinetic energy. In hot water, molecules move faster and have more kinetic energy, causing them to spread out and move more freely. This difference in movement affects the density, viscosity, and behavior of water in each temperature condition.
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.
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.
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.
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.
Is cold water more or less dense than warm water?
cold ocean waer has more dense than warm water.
How are the water molecules positioned in the hot cup?
In a hot cup of water, the water molecules have higher kinetic energy and are moving faster than in a cold cup. This results in the water molecules being more spread out and having increased motion, leading to a less structured arrangement compared to cold water.
Which has a higher entropy a hot water or a cold water?
Entropy is the measure of disorderness. Hot water --> more energy --> less stable --> more disorderness (than Cold water). Therefore, Entropy of Hot water is greater than that of Cold water.
Does warm water evaporate faster than cold water?
Yes, warm water evaporates faster than cold water because the molecules in warm water have more energy, allowing them to escape into the air more quickly.
Why does cold water have less volume than cold water?
Cold water has a higher density than warm water, which causes it to have less volume for the same mass. This is because the molecules are closer together in cold water, making it more compact.
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 has a higher density cold or hot water?
Cold water has a higher density than hot water. As water cools, its molecules come closer together, increasing its density. Conversely, hot water molecules are more spread out, resulting in lower density.
Why does hot air hold more water vapour than cold air?
Because the molecules in the hot air are more spread out, allowing water to easily form within the gaps of the molecules. Cold air is more dense and does not allow water to form easily between the molecules.
Can hot air hold more or less water than cold air?
Hot air can hold more water vapor than cold air. This is because warmer air molecules are further apart, allowing more space for water vapor molecules to exist in the air. Conversely, cold air molecules are closer together, limiting the amount of water vapor that can be held.
