Which statement accurately depicts what happens to water on the molecular level in a tea pot when it begins to boil?

a) the molecules begin to move farther apart decreasing their intermolecular forces and they escape the liquid state to enter the gas state.

b) .the molecules begin to move closer together overcoming their intermolecular forces which holds them together and they escape the liquid state to enter the gas state.

c) the molecules begin to move closer together decreasing their intramolecular forces and they escape the liquid state to enter the gas state.

(a) The molecules begin to move farther apart decreasing their intermolecular forces and they escape the liquid state to enter the gas state.

Explanation:

As we put tea pot  full of water on stove the heat transfer starts from surface of tea pot to the closest water molecule near the surface of tea pot, after becoming hot the water rises up and cooler water comes down. When water begins to boil their intermolecular forces begin to decrease and they start to convert in gaseous or vapor state.

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.
