Thermal Energy, Heat and Temperature

The video tutorial explains the differences between solids, liquids, and gases based on atomic motion. It discusses thermal energy as the total kinetic energy of atoms and how it varies in different states of matter. The concept of heat as energy transfer is introduced, along with how temperature is measured and its relation to kinetic energy. Practical examples illustrate how thermal energy affects everyday experiences, and methods to calculate energy transfer are explained.

What happens to thermal energy when two bodies at different temperatures come into contact?

Describe how temperature is measured and what it indicates about a substance.
