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

h let me think

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
