Imagine you want to build a small enclosure for some chickens on your property. You have an outside area for them that is made from barbed wire, and you have made a small inside, covered

enclosure for them out of bricks and cement which you would like to paint. You know that it can

get quite cold in winter in your area so you want the house to be as warm as possible for the

chickens. What colour paint are you going to choose to paint the outside of the chicken house?

Will it be a dark-coloured paint, such as brown or black, or a light-coloured paint, such as white

or yellow? Explain your choice.

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hey there!

mass = 6.75 g

volume =   9 cm³

therefore:

d = mass / volume

d   = 6.75 / 9

d = 0.7 g/cm³
