O The equilibrium constant changes.
Either the numerator or the denominator of the mass action expression will change.

TV
The concentrations change to maintain the original value of K.

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.

there is none because earth is stationary and flat.
