Understanding Thermal Energy
Thermal energy plays a crucial role in how substances behave under temperature changes. It encompasses the total kinetic energy of particles within a substance, influencing everything from cooking to climate science.
Definition of Thermal Energy
Thermal energy is the sum of the kinetic energies of all particles in a substance. This means that as the temperature increases, particles move faster, which raises the thermal energy. For example, when you heat water on a stove, its molecules gain kinetic energy and move more quickly. This increase directly affects boiling points and cooking times.
