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.
There are two reasons rivets are heated to red hot temperature during riveting: to soften the metal so that the head on the opposite side can be formed by hammering the metal, and to make the rivet longer while the head is being formed so that as it cools the rivet will shorten and pull the riveted metal plates tightly together.
The density will decrease because the heated metal contracts and its particles slow down.
because it can stay heated longer than other materials. It can also withstand a high temperature. .
when the ball is heated, it will pass through the unheated ring.
Heat just refers to increasing the temperature. The temperature range for a metal that is heated, theoretically speaking, only needs to be greater than 0 Kelvins.
When purified solid metal is heated under very high temperature it changes to liquid metal .This liquid metal is called molten metal .
When a rectangular piece of metal is heated and then left to cool down to room temperature, the rate of cooling will depend on several factors, including the size and thickness of the metal, the material composition, and the environment in which it is located. In general, thinner pieces of metal will cool more quickly than thicker ones, and metals with a high thermal conductivity, such as copper or aluminum, will cool faster than those with lower conductivity, such as steel or iron. Additionally, the cooling rate may be affected by the presence of any insulating materials or coatings on the metal, as well as the temperature and humidity of the surrounding air. It is difficult to provide a specific estimate of how long it will take for a rectangular piece of metal to cool to room temperature, as this will depend on many variables. However, you can expect that the cooling process will take longer for larger or thicker pieces of metal, and that it may take several hours or even days for the metal to reach equilibrium with the surrounding environment.

A bi-metal strip consists of two metals that expand by different amounts when the temperature changes, so it will bend when heated.
No, the volume of a metal increases as it is heated. It expands.
Non-metal... My science teacher finished teaching us about the periodic table of elements a month ago, and in my book it say's at room temperature it is a non-metal... I don't know whether it changes when it is heated but I would assume not, the same with when it is put somewhere below room temperature.
Platinum is used to measure temperature because when it is heated,This metal expands. When it is exposed to cold it retracts. The same thing happens with mercury.
It will become shorter as it cools. Heating causes most metals to expand in volume.
2.A metal object with a mass of 19 grams is heated to 96C and then transferred to a calorimeter containing 75 grams of water at 18C. If the water and metal object reach a final temperature of 22 what is the specific heat of the metal?

If heated sufficiently, yes. However, at room temperature (and up to over a thousand degrees Celsius), it is a solid.
