Change of State

The video tutorial explains the concept of changes of state, where a chemical's physical state changes without altering its composition. It covers the three phases of matter: solid, liquid, and gas, and how temperature affects molecular movement. Examples include water boiling and rock melting. The video also discusses condensation and everyday changes of state, concluding with a thought exercise on whether trees experience changes of state.
