Steel gets stronger
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.
water in a metal mug cools down quicker because the air around the mug cools the metal therefor cooling the water inside the mug
Radiator have metal fins which increases total surface area of the metal body which cooling effect and hence increase the efficiency to maximum cooling effect.
In accord with the second law of thermodynamics which states that heat spontaneously travels from a hotter object to a colder one, when metal touches something hot, the area where it touched something hot, will get warmer because of the increase in energy of the molecules, this warmth will spread throughout all the available metal until the metal and the hot substance it is touching have the same internal energy.
the metal will become hot
quenching
Hydrothermal solution
80 % 80 %
it melts.
Steel gets stronger
It becomes hot liquid.
Quenching , or quench hardeningis the process of rapidly cooling hot metal in a cold liquid. Its a process in which iron alloys and steel are hardened. This is done by heating the material to a certain temperature, and then cooling it rapidly in a cold liquid, usually water.
The metal object would contract, i.e it would shrink.
The first thing that happens when the body gets too hot is it beings to sweat. This provides immediate cooling which begins controlling body temperature.
it creates hot sand and warm water
