It depends on the metal.
If you drop sodium or potassium into water...well, let's hope you dropped it off the side of a bridge, because the reaction is pretty darned spectacular. Chemistry teachers used to take their classes on field trips to bridges so they could see this happen, but they don't let you do that anymore.
If you drop a non-reactive metal like steel or aluminum into water, it'll just sink to the bottom.
When hot metal is cooled rapidly it becomes harder and more brittle.
It will get hot, then cool down again. It is called Tempering; it hardens the metal.
it will explode and severely injure your hand
the cold piece of metal will attract because the hot piece of metal will turn a magnet
it buckles
choices are: The cold will flow from the metal into the hot water, causing the hot water to warm up and the metal to cool down. b. The energy from the hot water will flow into the cold metal, cooling the water down and heating up the metal. c. The cold will flow from the metal into the hot water, causing the hot water to cool down and the metal to warm up. d. The metal will cool down because the specific heat of water is high.
it cools down
Steel gets stronger
The only explanation of tempering is in metal manufacturing. Heat metal to cherry hot, plunge metal into water to quickly cool metal, hardened metal is created
It depends on how good a conductor the material is. Metal is a better warmth conductor then some plastics.
It melts rapidly.
It will cool down.
A tornado forms
quenching
the metal will become hot

Heat the metal red hot. To harden the metal, cool it quickly by dunking it into cold water. To get a soft metal, let it cool slowly.
Dropping a chunk of red hot copper in water will create a big hiss and the emission of steam from the container. The thermal energy of the copper will be transferred to the metal. The copper metal will cool rapidly and become brittle. If a copper wire is heated to a high temperature and quenched (cooled rapidly by immersion), it will harden and become less flexible than it was.
This is because ceramic generally has a very low heat transfer rate - if it is hot, it will stay hot for hours because the energy does not dissipate all that fast. In contrast, metals dissipate heat energy rapidly, which is why cold beverages are often put into metal cans - they become cool relatively rapidly.
it cools down
Your body gets hot and therefore produces sweat to cool it off
