It depends on the amount of carbon the metal has.
If the metal has too much carbon than it will become brittle.
If it doesn't then it will harden. (A lot of tools go through this process called Tempering)

What happens when metal and acid?
Acid + Metal = Salt + Hydrogen
Why sodium metal is stored under kerosene?
bcoz sodium is a alkali metal these metals when xposed to air they tarnish rapidly due to the formation of oxides on surface Save
What happens when your tongue freezes to metal?
It hurts.
What temperaure does metal burn?
Depends on the metal no metal does not burn it melts if u see a picture of metal burning it is impurities in the metal but after it melts i dont know what happens next
What happens to non metal in an ionic bond?
It accepts electrons from the metal and forms a negatively charged ion
What happens to metal when cooled?
It contracts.
What happens if steam is subjected to electric arc?
In the case of arc welding , moisture is superheated to steam , then further into Hydrogen and oxygen gasses, this usually produces a porous inferior weld, as the gasses are infused into the molten metal , and expand to form small voids , or pockets in the final cooled weld.
Why does metal become more brittle after being heated then cooled?
Not all metals do, and it depends on the rate at which the metal is cooled. Basically, in some metals the crystal pattern in the metal changes when heated- and if rapidly cooled, that pattern is sort of "locked in" to the metal. If that locked in pattern is harder or more brittle than the earlier state, the metal has become more brittle. However, heating and then SLOW cooling can make some metals less brittle- it is called annealing.
Why is tea cooled more rapidly by blowing on it?
because we put air from our mouth and the tea gets cold
When metal is cooled by ice what will the particles do?
The particles will contract.
What happens when you rapidly cool hot metal?
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.
How grain size depends on the temperature of liquid metal?
It doesn't, it depends on how fast the metal was cooled.
What happens when red hot copper is dropped in water?
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.
In which technology is magnetic levitation included?
There is a process for making spherical metal balls where the metal is suspended in an electromagnetic field while the metal is added then cooled.
What is the scientific term for heating metal and then rapidly cooling?
Annealing is a term used for when metal is heat hardened
How you can get the metal lid in the jar should you heat it or cool it?
You can try heating the metal lid to expand it and make it easier to open the jar. Alternatively, you can cool the metal lid to contract it, which may also help loosen its grip on the jar.
What is the difference between normalising and quenching?
In the normalising metal treatment process, the metal is cooled slowly and gradually while in quenching metal treatment process the metal is called very fast and abruptly.
