Which of these is an example of a mechanical wave

This is very true

Explanation:

The kinetic energy in a system is directly proportional to the temperature of a system.

The higher the temperature, the faster the particles of a system will move. From the kinetic molecular theory, we see that the temperature of a system is a measure of the average kinetic energy of the molecules.

In chemical kinetics, as the temperature increases, the kinetic energy of the system also increases.
