They shiver
alkali metals react violently in cold water
Mg does not react with cold water while Ca, Sr, and Ba react with cold water to form metal hydroxide and hydrogen gas.
People feared it. some thought U.S.A. could control the world and that's what started the cold war.
All metals, if they do react with water at all, react faster in steam than in water. However, the metals that react SLOWLY with cold water are the metals from Group-IIA(Magnesium, Calcium, etc).
Iron will slowly rust in cold water.
Gold does not react with water or steam. i wouldn't totally agree with the above statment. There are 5 metals which don't not just 1...these are: .lead .copper .mercury .silver .gold
potassium hydroxide
it gets cold
they react so aggressively and almost lead to destructive war
A reaction with water (hot or cold) is a chemical reaction.
Aluminum will not react with water at normal temperatures. Increase the temperature greatly, and just about any two things will react, though.
It will react in a UN suppressed way .
