A reaction with water (hot or cold) is a chemical reaction.
It is a chemical property.
Temperature is a physical property and it determines how hot or cold an object is. Heat flow is always from hot to cold.
yes ice being cold is a physical property. but once that ice melts it will be a chemical property because it is turning into another sunstence (water)
whether it is hot or cold
potassium hydroxide
It is a chemical property.
alkali metals react violently in cold water
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.
It floats on the surface of the water due to its low density.
Aluminum will not react with water at normal temperatures. Increase the temperature greatly, and just about any two things will react, though.
whether it is hot or cold
potassium hydroxide
If you heat up aluminum and then place it in cold water it can dissolve.
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
