1. Thermal expansion
2. If metals are heated in air some can react with oxygen.
When a metal bar is heated....the particles in the area of the metal bar that is hot start vibrating.. knocking into each other and passing the heat energy on to cooler particles. The cooler end that isn't heated still has a rise in temperature just not as much as the heated area because the heat has almost been diluted.
When a metal is heated to a high temperature, its particles vibrate more rapidly, increasing kinetic energy and causing thermal expansion. This can lead to changes in the metal's properties, such as increased ductility or changes in its crystal structure. At even higher temperatures, the metal can eventually melt and become a liquid.
The density will decrease because the heated metal contracts and its particles slow down.
when the ball is heated, it will pass through the unheated ring.
When a rod is heated, its ductility typically increases. The heat causes the atoms in the metal to vibrate more and the material to become more pliable, making it easier to deform without breaking. This increased ductility allows the metal to be shaped more easily.
its resistence considerably decreases
it wil expand
It heats up
i dnt know u tell me
The metal increases in hardness, a mechanical property. The process which transforms the metal hardness is called "quenching".
It will bend eventually because u have heated it up so much it wouldn't be able to function It becomes molten like the lava in the earth.
When a metal plate with a circular hole is heated, the metal expands due to the increase in temperature. As a result, the size of the hole also expands slightly. This phenomenon is known as thermal expansion.
No, the volume of a metal increases as it is heated. It expands.

Metal expands when it is heated. Since track is made of metal then it expands when it is heated by the sun.
