How do air pressure and precipitation determine the weather in a certain area? A:When the air pressure is higher, the air is cooler, and it is less likely for precipitation to fall.
B:When the air pressure is lower, it is harder for evaporation to occur and for the rain to form.
C:When the air pressure is higher, the humidity is higher, and the chance of precipitation is lower.
D:When the air pressure is higher, the air is warmer, and the chance of precipitation is higher.

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.
