what is the approximate density of a block of wood that measures 2 cm on each side, and has a mass of 16 grams?

2 g/cm

Explanation:

Formula for density:

m/v

to find the volume you can multiply 2 times 2 times 2 (since each side is 2 cm tall)

which is 8cm

16/8cm is 2 g/cm

Hope this helps!

explanation: no but i do not usually comment

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.
