Someone plz hello me ASAP it would be appreciated on question 7 btw

Kinetic Energy is the correct Answer.

yes

explanation:

search chemistry final b exam in google and a site called quizlet will pop up

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.
