Why does an iron wire expand when heated?
That's not just an iron wire - most materials expand when heated. This is called thermal expansion, and has to do with the fact that molecules move faster when it is hotter.
Does an iron ring expands or contracts on heating?
Most materials expand when heated.
Why does iron rims are heated red hot before 'fixing' them on cart wheels?
The rims expand slightly when heated. Once they're in place on the wooden wheel frame, they're cooled with water - making them shrink tightly to the circumference.
Why does a bimetallic bar made of copper and iron strips is heated the bar bends towards the iron strip?
Two metals making up the strip have different rates of expansion, so as heat is applied and the metals expand, one metal will expand faster than the other, causing that side to grow longer faster than the other side. Since the faster growing metal strip is bonded to the slower expanding, now shorter piece of metal, some movement must occur and the only means of movement is to bend.
How does the movement of molecules inside of a solid block of iron change as iron is heated?
Metals haven't molecules.
What happen when iron ball is heated?
The iron ball will expands and the iron ball will be hot .

Does an iron ring expands or contracts on heating?
Most materials expand when heated.
How much does an iron casting expand when heated?
because molecules dissolve or melt during the process and expands.
Why there is no substance formed when sulfur and iron is heated?
no,iron sulphide is made up when sulphur and iron is heated.
Why does iron rims are heated red hot before 'fixing' them on cart wheels?
The rims expand slightly when heated. Once they're in place on the wooden wheel frame, they're cooled with water - making them shrink tightly to the circumference.
What happens to iron filings and sulfur powder when heated?
When sufficiently heated, iron filings and sulfur react to produce a compound, iron (II) sulfide.
What happen to the hole of iron when heated?
oxides of iron are formed
What two products are formed when iron sulphide is heated in air?
Solid iron oxide and a poisonous called sulphur dioxide
What is the chemical equation of heated iron andsulfur?
chemical equation of heated iron and sulfur is as follows. FeS can be obtained by the heating of iron and sulfur:Fe + S → FeS.
Does iron expand when frozen?
no it don't
What happens when iron is added to oxygen?
Nothing unless they are heated. If they are heated it will become iron oxide. Which is the same material that we find the ground
