Explanation:

To determine what temperature measures, we analyze each option:

• Option A: Chemical bonds between particles are related to chemical structure, not temperature.
• Option B: Temperature is a measure of the average kinetic energy (a type of energy) of the particles in a substance. As temperature increases, particle energy (motion) increases, and vice versa.
• Option C: Density is mass per unit volume, unrelated to temperature's definition.
• Option D: Electrical charge of particles is about charge (like protons/electrons), not temperature.

So the correct answer is B.

Answer:

B. The energy of particles
