Hesham Mhd:
srry but, i did find nthn about the expansions O_o, can yu just expain it on here in brief plz?
nid404:
ohk...you wanted to know how they expand relatively right.
solids<liquids<gases
What else do you want to know..?
if you put pointers from the syllabus, it'll be easier for me
Hesham Mhd:
um ok, 'Describe Qualitatively the thermal expansion in solids, liquids and gases' ?
nid404:
Please go through the link I provided. It explains thermal expansion well...

In short:
solids have strong electrostatic bonds between particles that prevent them from expanding too much.
liquids have slightly weaker bonds and can expand a bit more
gases have NO forces of attraction and can expand to fill up container and exert GREATER pressure when heated.
