What is the term used to describe the charges on a polar covalent molecule?

a) Intramolecular
b) Dipoles
c) Intermolecular
d) Ionic

b) Dipoles

Explanation:

Learned this from some trash textbook.

An example of a polar covalent molecule is H2O.

Hydrogen bonds are basically dipole-dipole interactions between molecules of water. This is an intermolecular phenomena, but is specifically called dipole-dipole interaction. So the molecules themselves must be dipoles since the polar covalent bonds and differences in electronegativity cause partial positive and negative charges forming 2 poles, hence di-pole.

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
