My teacher always pairs me up with her son, and is always talking about how she wishes I was her daughter and how much I'm like her. She also sits me by him when we have to ride in the church van (we're in a small private online school, but we have PE together) Her son is super nice and smart. He's always complementing me and stuff... I think they are all trying to get us together lol. Any opinions on the matter?

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.

a polar bond is formed when electrons are shared unevenly between atoms
