the heat from hot water will heat the pipe, loosening the bonds between the molecules in the pipe and allowing for more oxygen molecules to enter, creating more rust much faster. cold water will do the opposite; it will make the bonds tighter and allow LESS oxygen in.
Both seem to be about the same
because sea water have a higher concentration than distilled water
Water could be poisonous as some hard metals would dissolve into in with out the presence of DO. As well, fish and aquatic plant would die if there was no oxygen. Drinking water would not taste as good either. A good thing that could occur would be that pipes would not corrode as quickly.
Iron will corrode (rust) in the body for a start. It is also not strong enough, the surface would also wear quickly.
1- Condensation because the tank is cooler then the ambient temperature when water is being drawn2- The tank is starting to corrode
Steel will corrode as the iron in it is more reactive than copper.
We don't use them because they react with water. Sodium reacts quickly and quite violently, magnesium is slower, but would still be eaten away. In fact we deliberately use blocks of magnesium on the hulls of ships so that they will corrode in preference to the iron hull.
the pipe with the hot water will.]The piping with cold water as many hydronic systems are over 100 years old and the piping looks as new as the day it was installedAs long as thermo stress and velocity are taken into consideration hot water lines can last longer then their cold countter parts as cold piping becomes more brittle over the years
Some canals might have potassium, some would not.
Yes pure water freezes more quickly than water with solvents (sugar, acid, etc.) like in Coke
If the water lilly was placed in an area with permanent water. it would probably do fine. Without water, however, it would quickly die.
Iron is prone to rusting in the presence of water. If you placed iron in the body, which is mainly water, it would rust and corrode. This means it disintergrates. It would also release dangerous amounts of Iron Oxides into the blood.
First make sure it can float. Then make sure that the materials used will not corrode too quickly, especially in salt-water. It would be advantageous to have a sail or a rudder. Shelter from the sun and a place to store food & water are essential.
