Valence shell electron pair repulsion (VSEPR) theory is based on the simple idea that electron groups one another through coulombic forces. ... According to VSEPR theory, the repulsions between electron groups on the atom of a molecule determine the geometry of the molecule. The preferred geometry of a molecule is the one in which the electron groups have separation possible. Consequently, for molecules having just one central atom, molecular geometry depends on (a) the of electron groups around the central atom and (b) how many of those electrons groups are

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.

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
