cos mofos is ill bot. Whatdaya want bro.
No they turn into different colours
By chemical reaction.
yes!
Certain metals can be blackened or streak by perspiration...
Black or brown but is another chemical is mixed it can turn different colours
A bimetallic strip is commonly used in thermostats to regulate temperature. When the strip is heated, the two metals with different coefficients of expansion cause it to bend, which in turn triggers a switch to turn on/off a heating or cooling system. This mechanism is used in devices such as ovens, refrigerators, and kettles.
It can make itself change from blue to green, red to brown and yellow to orange.
No, real gold does not turn black when you burn it. When heated, gold will retain its color and may become softer or deform, but it will not change color like other metals that oxidize when burned.
Its called a bi-metallic switch, which switches off when the kettle boils, as the switch is made from two layers of different metals, which expand at different rates when heated, which causes the sandwich of the two metals to "bend" when it heats up.

When heated, metals like iron, steel, and titanium can turn red due to oxidation. This process forms a layer of iron oxide on the surface, giving it a reddish color.
Most heated mirrors turn on along with the rear window defrost switch.
