What intermolecular forces are present in each of the substances?

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer

plz give brainliest

1. they vary with a higher number because boiling is way hotter than melting
