Question

which is the term used for the measurement of the average kinetic energy of the particles of a substance?
a) density
b) mass
c) length
d) temperature

Explanation:

• Option A: Density is mass per unit volume, not related to particle kinetic energy.
• Option B: Mass is the amount of matter, not a measure of kinetic energy.
• Option C: Length is a dimension, not related to particle energy.
• Option D: Temperature is defined as the measure of the average kinetic energy of particles in a substance.

Answer:

D) temperature
