Question

Which of the following statements best describes the relationship between temperature and kinetic energy of particles in a substance?

A) As kinetic energy increases, temperature decreases.
B) As kinetic energy decreases, temperature is not affected.
C) As kinetic energy increases, temperature increases.
D) As kinetic energy decreases, temperature increases.

Answer 1

As kinetic energy increases, temperature increases.

Step-by-step explanation:

According to the kinetic-molecular theory, the temperature of a substance is proportional to the average kinetic energy of its particles. Therefore, as the kinetic energy of the particles increases, the temperature of the substance also increases. This is because when a substance is heated, some of the absorbed energy increases the motion of the particles, resulting in a higher temperature.
