Fill in the blanks below to complete the hypothesis for this lab. It should answer the lab question, “What is the effect of molecule size on a molecule’s ability to diffuse across a semipermeable membrane?” If molecules are small enough, then

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.

metric time was an attempt to create a standard unit of time based off of 10, but it never took off an is not included in the metric system (si)

nuclear fission produces elements that are heavier than helium.

the elements that are used in nuclear fission and their products are much heavier than helium.
