Typically, if you have hot water that is white, you have a water softener in your home. The water softener adds a small quantity of salt to the water to make it feel softer to the skin. This tends to break down some of the minerals in the water and also make it less likely to etch glasses in a dishwasher.
The water softener is typically not plumbed into the cold water, and this is why the cold water remains clear.
It depends on if it clears up after being left to stand for a while. If it does clear up then it is only air bubbles because of the change of temperature from hot to cold in the lines. If this the case it is safe. If it does not clear up and is not air bubbles it may be chlorine or calcium deposits in the lines which will not kill if you really need some water, but not good for continuous everyday consumption and cooking.
Hot, categorically.
It either gets,hot or cold depending on what water you put in.
A hot towel will not clear up a cold sore.
Water can be hot or cold if you want
Brown sugar is soluble in water- and it's solubility increases as the temperature increases (i.e. the hotter the water, the more brown sugar will dissolve!) This is why you can put brown sugar in your tea- while it is hot, it will all mix in, but if you make it with cold water, much less will dissove.
Hot water may have more air in it, if you look closely you will see that there are all individual tiny, tiny little bubbles in there, looking at it as a whole, it looks white. If you notice it will clear from the bottom, up. Indicating that the bubbles are rising. I can say definitely it's air, but why there's more air in hot water than in cold water, that I couldn't say - maybe it has something to do with the molecules, their size and how fast they are moving. Hot water has the same amount of air in it as the cold because it is the same water. However the warmer the water the less disolved gases it can hold. Once liberated from being under pressure in the pipe and poured into a glass the gases come out of solution and into the air once this stops the water appears clear. It is much like opening a bottle of soda. The white colour may be hydrogen generated from inside the hot water unit. It is produced as a function of the water quality, temperature and the type of annode in the unit.
Unless it's all white laundry, warm water is best.

Hot water is less denser than cold water and has a greater temperature.
