Theories of Heat
- Caloric Theory: Heat is a fluid-like substance that flows from hot to cold objects.
- Kinetic Molecular Theory: Heat is the motion of particles, and faster-moving particles correspond to higher temperatures.
Heat Transfer
- Conduction: Transfer of heat through direct contact.
- Convection: Transfer of heat in fluids due to particle movement.
- Radiation: Transfer of heat via electromagnetic waves (e.g., sunlight).
Practice Questions
- Explain why metal feels colder than wood at the same temperature.
- Describe how convection currents work in boiling water.
- Why does heat transfer stop between two objects?
