Tap is better, because it has been made cleaner by machines etc
the answer is simple tap water contains minerals to help wash dishes bottle water is much cleaner
you really should pay attention in class
It isn't. This is a fallacy that if you pay a higher price for water that it is better. Studies have shown that tap water is just as good as "spring water."
When designing and constructing a spring-fed water tap, the specific location of the spring must be taken into consideration. Any plan for tapping will include a drain for surface water, a spring eye location, an overflow, a supply pipe, and a drain.
Saltwater is more dense than fresh water, hence it provides more buoyancy (the force that pushes up). Your solid will seem less heavy in the salted water.
Tap water, Spring water and Fresh water
Bottled spring water is often not better for people because it does not undergo the same rigorous testing for impurities as a city's municipal water supply, which is the origin of tap water.
In order for water to be supercooled, there must not be impurities that can act as nucleation sites within the water. Spring water should work, though tap water would more than likely need to be purified before it would be supercooled, as by reverse osmosis.
Some people do not believe it but the best water to use in your betta fish tank is tap water. Bottled and distilled water has been "purified" and does not have the minerals that your Betta fish needs. If your tap water is so bad that you do not even drink it, than use spring water.
Tap water can affect plants because some tap water may have excess salts that can prevent the roots from absorbing nutrients and enough water. Chlorine and fluorine can curl leaf edges and produce leaf spots and singeing.
Spring water is best, as tap water may have too much chlorine added to it at the reservoirs.
Well, first of all natural water would probably be dirty and unfiltered, such as a natural pond and lake. Spring water would be manufactured out of spring water and would be much cleaner at that. If the natural water you are thinking of is different then this answer the natural water you are thinking of is probably everyday water that you drink, and more than likely doesn't come from a spring. Spring water also is found in a water bottle, and natural water can be found through faucets at home. Because your water is natural, isn't it?
