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.

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.


Does hot water have more energy than cold water and why?

Yes, hot water has more thermal energy than cold water because its molecules are moving faster and have higher kinetic energy. This increased molecular motion results in higher temperature and thermal energy content in hot water compared to cold water.


How can the hot water be at a higher pressure than the cold mains in an unvented system?

In an unvented system, hot water can be at a higher pressure than the cold mains due to the presence of a pressure-reducing valve on the cold water supply. This valve controls the pressure of the cold water coming into the system, allowing the pressure of the hot water, which is heated and stored at a higher temperature, to be higher. Additionally, the expansion vessel in the system helps regulate pressure fluctuations by absorbing excess pressure from heating water.


Is water hot or cold?

Water can be either hot or cold depending on the temperature. Water at room temperature is considered neither hot nor cold.


What happens when a hot soda can is placed in cold water in the hot soda can in cold water experiment?

When a hot soda can is placed in cold water in the hot soda can in cold water experiment, the can undergoes a rapid cooling process. This causes the air inside the can to contract, creating a lower pressure inside the can compared to the outside. As a result, the higher pressure outside the can pushes the can inward, causing it to crush or implode.

What has a higher rate of evaporation hot water or cold water?

A higher rate of evaporation has hot water.


Is pure ammonia soluble in hot or cold water?

Ammonia is soluble in both hot and cold water, with a higher solubility in cold water.


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.


What is the difference between the hot and cold side of a faucet?

The hot side of a faucet is connected to the hot water supply, which is heated, while the cold side is connected to the cold water supply. The hot side releases water at a higher temperature, while the cold side releases water at a lower temperature.


When you add hot water to cold water the cold water gets warm because of what?

That would be convection. Thermal diffusion of energy from a high concentration to a low concentration. Depending on the application or context, the loss of energy can be reffered to as entropy as well.


What gets cold first hot or cold water?

Isn't cold water already cold? I would say cold water gets cold first. I've heard that hot water freezes faster than cold water.


Does hot water have more energy than cold water and why?

Yes, hot water has more thermal energy than cold water because its molecules are moving faster and have higher kinetic energy. This increased molecular motion results in higher temperature and thermal energy content in hot water compared to cold water.


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.


Is it true that cold water is hot?

No, cold water is not hot. Cold water is at a lower temperature than hot water.


Do bubbles last longer in hot water or cold water and why?

Bubbles typically last longer in cold water than in hot water. This is because cold water has a higher concentration of dissolved gases, which helps maintain the integrity of the bubble's structure. In contrast, hot water has lower gas solubility, causing bubbles to burst more quickly.


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.


Is sulfur dioxide more soluble in hot or cold water?

Sulfur dioxide is more soluble in cold water than in hot water. As the temperature of water increases, its ability to dissolve gases decreases, so sulfur dioxide will have higher solubility in cold water.
