Question

examine the model of the different states of matter. select all of the statements that accurately describe the particles in differing states. a gases contain less particles b gases have the greatest kinetic energy c energy is removed in the change from a liquid to a gas d energy is added to change from a solid to a liquid state

Explanation:

• Option A: Gases don't necessarily have fewer particles; it depends on the amount of substance.
• Option B: Particles in gases move freely and have the highest kinetic energy among the three states.
• Option C: Energy is added (endothermic) when changing from liquid to gas (vaporization).
• Option D: Energy is added (endothermic) to change from solid to liquid (melting).

Answer:

B. Gases have the greatest kinetic energy, D. Energy is added to change from a solid to a liquid state
