Ared blood cell placed in distilled water will swell due to the diffusion of

Osmosis

Explanation:

Particle in water move from low concentration to higher concentration in semi-permeable membrane. The particle of water would be less concentrated therefore the water would move into red blood cell therefore building in mass due to water and therefore swelling

Option (C) is the correct answer.

Explanation:

Spontaneity is defined as the degree of randomness. This means that more randomly the particles of a matter or substance are moving more it will has the spontaneity.

For example, particles of a gas are more spontaneous than particles of a liquid.

Thus, we can conclude that spontaneous reactions always result in increased disorder of the system.
