Exam Year: 2021

Solution:

Temperature is a measure of the average kinetic energy of the particles in a substance.

The measure of the average kinetic energy of the particles in a substance is known as _____. (2021)

The measure of the average kinetic energy of the particles in a substance is known as _____. (2021)

Step 1: Understand what kinetic energy is. Kinetic energy is the energy that particles have due to their motion.
Step 2: Recognize that all substances are made up of tiny particles that are always moving.
Step 3: Know that the average kinetic energy of these moving particles gives us an idea of how hot or cold a substance is.
Step 4: Learn that this average kinetic energy is measured using a term called 'temperature'.
Step 5: Conclude that the answer to the question is 'temperature'.

Temperature – Temperature is a physical quantity that represents the average kinetic energy of the particles in a substance, indicating how hot or cold the substance is.
