Cold water helps keep the DNA intact during extraction.
Cools things down. That sounds glib, but it's essentially true.
no
Dissolving is caused by the small rapid movements of the atoms or molecules. The faster they are moving, the better substances dissolve. As the molecules have more energy and therefore move faster in hot water, substances dissolve better there.
Because the hot water is less dense than the cold water, so the dye molecules have a better chance of making it through the less compact hot water.
A better word than cold can be FROZEN .................
There are different opinions concerning this topic because their effects are somewhat different. But majority agree that tepid water is more effective than cold water. You can read their effects in detail here: http://scienceray.com/biology/ecology/drinking-cold-water-or-warm-water-which-one-is-more-effective/
is cold water a better conductor than hot
yes.
It can, but hot water works better because it helps to dissolve grease and hardened food better than cold.
cold is better cuz when your in the ocean is the water hot or cold cold
There is no evidence that supports warm water is better than cold water in heart attacks. There are many symptoms for heart attacks such as a pain in the left arm.
Yes, It removes thirst better than warm water.
no
Cold water is cheaper and really there's no difference but it could be easier on your clothes!

Warm water is a better cleaner because cold water fuses the stain even more so to the fabric, where as warm water draws the stain away from said fabric.
Endotherms are significantly better adapted to cold water and cold environments in general than ectotherms. This is because endotherms can operate at a temperature that is maximally efficient for the function of their enzymes.
because it is refined and it has small particles...
