When a 5.0cm long raw potato chip was placed in water and left for 30 minutes, its length was found to have increased to 5.5cm. Use your knowledge of the particulate theory of matter to explain this.

due to diffusion as hypotonic solution

diffusion is the movements of particles from higher concentration to lower concentration

in hypoxic solutions the concentration is lesser in the inside compared to the outside.

so water enters thus making the potato larger.

hope it helps : )

potato chips making me hungry

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.

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.
