Salt dissolves better in hot water than in cold water, but gases dissolve better in cold than in hot water.
The reason salt dissolves better in hot water, is that heated water molecules have greater kinetic energy. Since the molecules move around more, the attractions between water molecules are weaker, and salts are able to enter.
The reason gases dissolve better in cold water, is that gases want to escape water. However, they are trapped by the water molecules. When the water is hot, the molecules move around more, and there is more space between them. Gases are then able to escape. When the water is cold, the molecules stick close together, and trap the oxygen.
In other words, the same conditions that help salts dissolve in water, allow gases to escape water.
What else can I help you with?
What is less dense warm air or cold air?
Warm air is less dense (lighter) than cold air..that is why warm air rises and cold air settles
What is the difference in density between warm and cold air?
Warm air is less dense than cold air because the molecules in warm air have more energy and are more spread out, resulting in lower density. Cold air is denser because the molecules are closer together and moving slower.
Is warm air dense?
No, warm air is less dense than cold air because the molecules in warm air have more energy and are spread out more, resulting in lower density.
Do warm fronts have steeper slopes than cold fronts?
No, cold fronts typically have steeper slopes than warm fronts. Cold fronts tend to move more quickly and have a more pronounced temperature difference across the front, resulting in a steeper slope. Warm fronts are more gradual in their slope and advance more slowly.
What kind of density do warm air and cold air masses have?
Warm air masses are less dense than cold air masses because warm air molecules have more energy and are more spread out, leading to lower pressure. Cold air masses are denser because cold air molecules are closer together and have less energy, resulting in higher pressure.
Does cold air contain more oxygen than warm air?
Yes, cold air typically contains more oxygen than warm air. This is because cold air is denser and can hold more molecules, including oxygen.
Does cold air have less oxygen compared to warm air?
Yes, cold air typically has more oxygen compared to warm air because cold air is denser and can hold more oxygen molecules.
Why aquatic species feel comfortable in cold water rather than warm water?
Fish survive better in cold water then in warm water because :- 1) Cold water has more oxygen and more oxygen means more microscopic life which means more food. 2) In Cold water there is more solubility of the carbon dioxide released by the fish
What is cold air more than warm air?
Cold air is more dense than warm air.
What is more dense cold water or warm?
cold ocean water is more dense than warm water
Are there more cold receptors or warm receptors in the skin?
There are more cold receptors in the skin than warm receptors.
Does cold air hold more than warm air?
No. Warm air is capable of holding much more water vapour than cold air.
Is cold air more or less dense compared to warm air?
Cold air is more dense than warm air.
Is cold water more or less dense than warm water?
cold ocean waer has more dense than warm water.
Why is cool air denser than warm air?
There are more atoms in cold air than warm.
Eyeballs feel warm?
kinda its more like room temperature but its more warm than cold
Is the air more saturated in cold or warm weather?
Warm air holds more moisture than cold air. In warm weather, there is increased evaporation of sea water.
