2.2.2 Specific heat capacity (1 questions)
When an object is heated, its temperature increases. This increase in temperature can be explained by the kinetic theory of matter. The kinetic theory states that all matter is made up of particles (atoms or molecules) that are constantly in random motion. The average kinetic energy of these particles is directly proportional to the absolute temperature of the object.
Heating an object provides energy to its particles. This energy is transferred to the particles, increasing their kinetic energy. As the particles gain kinetic energy, they move faster and with greater force. The average speed of the particles, and therefore their average kinetic energy, increases. This increase in the average kinetic energy of the particles manifests as a rise in the object's temperature. In essence, a higher temperature means the particles are moving more vigorously.
The relationship can be summarized as: Temperature ∝ Average Kinetic Energy of Particles
