biotic factors
This change of state happens when a solid becomes a liquid by heating.
MELTING
This separation technique is used in separating alcohol and water and relies on the physical property of matter.
distillation, and boiling point
How many different shapes of orbitals are present in a energy level 3?

Factors such as: wind, temperature
abiotic (climatic)
This direct change of state skips the liquid phase, as when dry ice turns into carbon dioxide gas.
SUBLIMATION
mass and volume are examples of this type of property, because they depend on how much substance you have.
PHYSICAL/EXTENSIVE
This energy level can hold up to 8 electrons in total.
ENERGY LEVEL 2
This quantum number determines the shape of the electron cloud (s, p, d, f).
