When does uranium change state?
Uranium changes state as any other material does. We know uranium is a metal, and it can be heated and melted, or heated even more and vaporized. It is the same process that might be used on iron or aluminum.
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 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.
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 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
What is molten ore?
When purified solid metal is heated under very high temperature it changes to liquid metal .This liquid metal is called molten metal .
Why does a bi-metal strip bends?
A bi-metal strip consists of two metals that expand by different amounts when the temperature changes, so it will bend when heated.
Will the volume of metal decrease if it is heated?
No, the volume of a metal increases as it is heated. It expands.

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.
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.

Many metal hydroxides decompose when heated to yield metal oxides and?
H2O i think
