When the metal ball is heated can it go through the metal ring?
when the ball is heated, it will pass through the unheated ring.
What happens to the density of a heated iron block?
The density will decrease because the heated metal contracts and its particles slow down.
When a metal powder is heated in open dish it turns black which metal is that?
The metal might be copper. When copper is heated, it reacts with oxygen in air forming copper oxide which is black in colour.
Name one metal which does not react with oxygen when heated?
Brooks metal ;)
What happens to the particles in a metal when the metal is heated?
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 heated metal cools down it?
It loses thermodynamic energy.
Will the volume of metal decrease if it is heated?
No, the volume of a metal increases as it is heated. It expands.
Why a glass jar can be easily opened if the metal lid is heated?
because metal will expand when it has been heated up
When the metal ball is heated can it go through the metal ring?
when the ball is heated, it will pass through the unheated ring.
Why do train tracks expand?
Metal expands when it is heated. Since track is made of metal then it expands when it is heated by the sun.
How do you make swords?
You can make a "toy" sword from wood by carving the edges down. To make an actual sword from metal, a block of heated metal is pounded, then cooled, then repeatedly heated and flattened again to make it into a hard, narrow strip. This provides strength to the metal. If liquid metal were simply poured into a flat form, it would not have the required toughness.
What happens to the density of a heated iron block?
The density will decrease because the heated metal contracts and its particles slow down.
What expands when heated?
metal is a solid that expands when heated also of course when liquids are heated and change state into a gas they expand but metal is cool because it expands before it changes state
When a metal powder is heated in open dish it turns black which metal is that?
The metal might be copper. When copper is heated, it reacts with oxygen in air forming copper oxide which is black in colour.

Where does the energy in a heated up metal block go after it has cooled down?
The heat energy radiated away, or was transferred to the air around it, or to surfaces it touched.
Many metal hydroxides decompose when heated to yield metal oxides and?
H2O i think
