If you heat aluminum it expands in volume,what happens atom"s volume ,does it change?

Question

How do you explain water not changing volume after adding heat above its 100 degree C boiling point?

Answer 1

atoms volume dose not change the distance between atoms increases tell it become liquid and with More heating the distance become larger according to the following the transformation from one phase to another
ΔG=ΔH-TΔS
when ΔG is minus then the phase transfor mation begins

Answer 2

Naw, just the spaces between atoms. Think of it like this: if you brought a liquid (like, say, Jello or something) to a boil, the volume increases because there are air bubbles in the mix. But if you brought it to a boil and immediately turned it off so that there was negligible loss of liquid due to evaporation, it would be the same volume as before. Think of the heat as "air bubbles"--it's the same stuff, but with more space in between the little molecules of Jello. Atoms just have more space in the mix, but not in the individual teeny little parts. If you want to change the volume of an atom, you gotta get like an atom smasher or something and spin the atoms around super fast and then, SMACK! Atom bits! But that's for *smaller*--I don't know how to make an atom bigger. Put some more electrons around it--maybe that would make it a little bigger. But that's a whole 'nother topic.

Answer 3

The atom's volume doesn't change. Just the vibration increases 2 a larger extent

Answer 4

NO. Get this straight while heating the distance between two particles increases so they appear to enlarge thus if you heat aluminium its atoms volume doesnt change

Answer 5

The expansion is caused by the molecular bonds of the atoms loosening, Atoms in solids are very compacted, in Liquids some what compacted, but free to move around, in Gases free to move around completly, the state is dependent on the material and temp. The atoms them selves remained unchanged

Answer 6

The volume of the atom does not increase. Atoms keep their volume, however, their distance from one another increases which allows for flexibility and softening. Atoms do not change....only their distance and velocity.

Answer 7

No it is the distance between the atoms that changes.
