Absolute temperature is proportional to the average kinetic energy of the atoms. True or false?

True.

To understand why absolute temperature is proportional to the average kinetic energy of the atoms, we need to look at the concept of temperature and kinetic energy.

Temperature is a measure of the average kinetic energy of the particles in a substance. Kinetic energy is the energy that particles possess due to their motion. The higher the temperature, the greater the average kinetic energy of the particles.

According to the kinetic theory of gases, temperature is related to the average kinetic energy of the atoms or molecules in a substance. The kinetic energy of a particle is given by the equation: KE = (1/2)mv^2, where KE is the kinetic energy, m is the mass of the particle, and v is its velocity.

As temperature increases, the average kinetic energy of the particles also increases. The atoms or molecules move faster, leading to an increase in their kinetic energy. Similarly, as the temperature decreases, the average kinetic energy of the particles decreases, resulting in slower motion.

Therefore, we can say that absolute temperature is proportional to the average kinetic energy of the atoms.
