Question

The densities of the liquid and solid states of a substance are often similar. Explain.
GK
Density is related to intermolecular or other inter-particle distances. These are dependent on molecular or ionic radii, intermolecular attractions (or other cohesive forces), dispersive forces (repulsions) and molecular kinetic energies (molecular speeds). All these factors are similar in solids and liquids.

a roll of aluminum has a mass of 1.08kg. what is its mass in pounds? (1 lb= 435.6g)
tjcgjdt
an easier answer is both solid and liquid particles
are held together by attractive force
