Water vapor cools and comes together to form a cloud. this is an example of what change in state?
condensation
evaporation
melting

The question says, 'water vapor comes together to form a cloud. This is an example of what change in state. The correct option is condensation. Condensation occurs when water collect as droplets on a cool surface when it comes in contact with humid air. It involves the conversion of a vapor to liquid.

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.
