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.
When you boil water, the bubbles that you see in the boiling are the dissolved gases (oxygen) being eliminated from ther water. Hence unboiled water has a lot of dissolved gases. Boiled water has very little dissolved gas. Even below a liquids boiling point, the warmer a liquid becomes the less gas it holds in solution. The oceans of the world hold a lot gas in solution, carbon dioxide being one of them. If the oceans warm up, then some of this carbons dioxide will be eliminated into the atmosphere.

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.
Cold water is a mixture when it contains dissolved substances, such as salt or sugar, but it is considered a solution when those substances are uniformly distributed and not visibly separate from the water. Pure cold water itself, without any solutes, is simply a substance. In summary, whether cold water is a solution or a mixture depends on the presence of dissolved materials.
Solid chemicals are dissolved faster in hot 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.
Cold water can dissolve less salt than can hot water. Therefore, you would reach the saturation point faster with cold water.
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.
