Ineed with this explain why gases condense when they are cooled.

The expansion of gases takes place because of kinetic energy provided by heat which excites the molecules and causes them to move further apart. On cooling the atoms in a gas lose their energy and slow down coming closer together.

hope this helps lol

There is one s orbital, and there are three p orbitals, five d orbitals, and seven f orbitals. thus, the answer is b. do not confuse the number of orbitals in a subshell with the number of electrons the subshell can hold. each orbital can hold two electrons, so the capacity of an nf subshell is 14 electrons.
