It turns into a silvery liquid and remains at room temperature while giving off colourless gas

When sufficiently heated, iron filings and sulfur react to produce a compound, iron (II) sulfide.
thermal
when green powder is heated, it turns black and a gas is produced. in irreversible changes, new materials are always formed. given that a gas is produced, which is a new material, heating green powder is an irreversible change.
When solids are heated they turn into liquid
it is a red powder

calyx is not an element because it is in powder form, elements cannot be broken down into any simpler substance by chemical methods.
Do you mean iron powder mixed with sulphur powder? Fe(s) + S(s) ---> FeS (iron sulfide)
When sufficiently heated, iron filings and sulfur react to produce a compound, iron (II) sulfide.
Powder Coating I think
It turns into a white powder and when water is then again added to the deydrated copper sulphate it turns back to its original colour

When matter is heated it will expand
Bracteole and calyx
