Hund's Rule<span>. </span>Hund's rule<span>: every orbital in a subshell is singly occupied with one electron before any one orbital is doubly occupied, and all electrons in singly occupied orbitals have the same spin. so D. is the answer</span>
Answer:
so the earth has an atmosphere, which holds in all the oxygen, it has gravity, and it has the green house effect, causing the earth's warmth to stay in it's atmosphere
Answer:
Hi
The water molecule is composed of three atoms: an oxygen atom and two hydrogen atoms. Very strong electromagnetic forces hold the atoms inside the molecule.
A parallel electromagnetic attraction exists between the molecules individually. Water molecules are constantly moving and continuously form and break bonds with other molecules. As the temperature rises, the molecules move faster and the bonds weaken, changing their state to gas. This is called the boiling point. At this stage, the distance between water molecules is large and intermolecular bonds are almost non-existent.
Explanation:
occurs in fluids
Explanation:
Convection is a mode of heat transfer that occurs in fluids.
There are three types of heat transfer:
conduction convection and radiation
- Conduction is a mode of heat transfer that involves an actual contact between the molecules of the medium. It occurs mostly in solids
- Radiation uses electromagnetic waves to transfer heat between two bodies or places. It does not require a material medium. The heat of the sun reaches us by radiation.
- Convection is a mode of heat transfer in fluids. It involves the density differences between hot and cold liquids and gases.
- Water boils by convection currents.
