What is the key difference between solids and liquids
definite shape
Explain the motion of liquids
the individual molecules have motion, but the system has no net motion.
Does the shape of a solid vary?
yes. the lattice structure DOES NOT vary because it is a microscopic property
convection current
flow of liquid or gas
