What occurs when a substanc eis converrted from liquid to gas at the normal boiling point potential energy of the system increases the distance between moleucles increases.

they are both synthetic elements

explanation:

d

c. electrical charges of ionic bonds.

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
