The heating and cooling of molecules will make what change their state of matter

Explanation:

Kinetic energy is defined as the energy obtained by an object. Also, kinetic energy is directly proportional to temperature according to the following relation.

                 K.E =

So, when we increase the temperature by heating a substance then its molecules tend to gain more kinetic energy due to which more number of collisions occur. As a result, state of matter changes from solid to liquid and from liquid to gas.

Whereas if there occurs a decrease in temperature then it means kinetic energy of molecules will decrease. Hence, molecules will come closer to each other.

Therefore, state of matter will change from gas to liquid and from liquid to solid.

Thus, we can conclude that the heating and cooling of molecules will make kinetic energy change their state of matter.

convalent bond :

is a chemical bond formed by the sharing of electron between 2 atoms.

it is the direct chemical bond between 2 atoms.

in bond formation atoms are involved here.

electrovalent bond:

is a chemical bond defined as electroststic attraction between 2 atoms.

it is the electrostatic attraction between 2 atoms.

in bond formation, ions are involved here.

hope it

and ur welcm
