A reaction with water (hot or cold) is a chemical reaction.
It is a chemical property.
Mg does not react with cold water while Ca, Sr, and Ba react with cold water to form metal hydroxide and hydrogen gas.
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)
potassium hydroxide
Conduction of heat is a physical process by which heat energy is transferred through a material without any actual transfer of the material itself. It is not a physical property of the material itself, but rather a characteristic of how heat energy is conducted within a material.
It is a chemical property.
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.

Iron will slowly rust 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).
The physical property of reactivity is observed when lithium reacts with cold water, producing hydrogen gas and forming lithium hydroxide. This reaction occurs because lithium is a highly reactive metal and readily reacts with water.
Aluminum will not react with water at normal temperatures. Increase the temperature greatly, and just about any two things will react, though.
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
Yes it does react. It forms Calcium hydroxide and makes the water hot. It is because the reaction between CaO and water is an exothermic reaction
Nickel Doesn't react with water under normal conditions
