Why does the melted candle have more mass than the solid candle did??

Question

My chemistry question, but I do not know the answer. Help me please

Answer 1

      it could be for the sole reason that the solid candle comes compressed and after melting it decompresses.

Answer 2

no.

only a physical changed happened because the change can be reversed....so it weighs the same...

i could give a longer explanation, but if you don't know the answer to that, you probably wouldn't get it.

Answer 3

Your question violates the law of conservation of mass/matter. If you melt something it's mass does not change. Perhaps your candle got contaminated with something else after you melted it which is why the mass appeared to have increased.  

Answer 4

as an object is warmed, the molecules separate further apart. wax, however, will fill in those holes.

Answer 5

It doesn't. Melting is only a change of State of the wax from solid to liquid. No other changes occur. (In actual fact, the heated wax will lose some of its mass by some vaporisation of the wax and will therefore have a little LESS mass than the solid.

Answer 6

Melting won't change mass.

The molten wax will have a higher DENSITY though, because the

crystal structure has more voids than the liquid.

That's why the solid floats in the liquid as you melt it.

Density is mass per volume, (M/V),.

It will be important later to know the difference.
