The escape of molecules from the surface of a liquid is known as .

Further Explanation:

Phase transition is defined as the change from one state to another state but no change in chemical composition is observed. It is also known as a phase change, state change or physical change.

Sublimation

It is the process by which a substance directly gets converted from solid to vapor phase, without going through the liquid state. Naphthalene and dry ice are substances that undergo sublimation.

Condensation

It is the phase transition that occurs when vapors are converted into liquid. This is done by changing the temperature and pressure of the substance.

Evaporation

In this process, liquid changes into vapors. Here, temperature has to be elevated or heating is done. Energy is used up in the substance and therefore it is an endothermic process.

Boiling

It is a phase change in which liquid is converted to a gaseous state when liquid is heated to its boiling point.

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

⇌(double head arrow) means reversible reaction).
