The dissolution is an endothermic process.
Cold water generally has more dissolved gases than hot water. This is because gases are more soluble in colder temperatures compared to warmer temperatures. When water is heated, its capacity to hold dissolved gases decreases.
Yeast is dissolved in warm water rather than cold water when making bread because the warmth helps activate the yeast cells, promoting fermentation and allowing the bread to rise. Cold water can slow down the activation process and may not be as effective in producing the desired outcome in bread-making.
Cold water can hold more dissolved oxygen than hot water. This is because the solubility of oxygen in water decreases as the temperature increases. Therefore, cold water has the ability to hold more oxygen than hot water.
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.
Water is more dense the colder it becomes. It is also more dense the saltier it becomes.

Somewhat, but it dissolves faster in warm water.
Water
yes
Sand is not soluble in any water. It can be suspended in water, but never dissolved.
Solid chemicals are dissolved faster in hot water.
Cold water can dissolve less salt than can hot water. Therefore, you would reach the saturation point faster with cold water.
The exact number of sugar cubes that can be dissolved in cold water depends on the size of the sugar cubes and the volume of water, but generally speaking, you can dissolve 1 sugar cube per 1 ounce of cold water. Keep in mind that the solubility of sugar decreases as the water temperature decreases.
it doesnt easily dissolved on a cold water because of its temperature
In the polar regions, there is more dissolved oxygen in the ocean water. The cold water is able to hold more dissolved gases than warm water.
Water salinity describes the amount of salty minerals dissolved in a sample of water. It would therefore make no difference whether the water is warm or cold, since you would have the same amount of salt dissolved in the water per cm3 of water. Salinity would change if you added more water, or if the water was so hot that some of it evaporates, leaving all the dissolved solids behind, but decreasing the amount of water it is dissolved in.
