Heat and Energy Transfer

Categories Physics

Course Description

Heat and Energy Transfer is a foundational physics module that explores how thermal energy moves through matter and space. From sunbathing on a summer day to boiling water for tea, heat transfer is constantly shaping our environment and technology.

This lesson breaks down the difference between heat and temperature and introduces the three main mechanisms by which heat travels—conduction, convection, and radiation. Whether you’re a student, engineer, or curious observer, this course connects everyday experiences to the science behind thermal energy.

What You’ll Learn

🔥 By the end of this lesson, you’ll be able to:

  • Distinguish between heat and temperature:
    • Heat is the transfer of thermal energy between systems due to a temperature difference
    • Temperature is a measure of the average kinetic energy of particles in a substance
    • Understand why two objects can have the same temperature but different amounts of heat
  • Explore the three primary methods of heat transfer:
    • Conduction – heat transfer through direct contact (e.g., a metal spoon warming in hot soup)
    • Convection – heat transfer through fluid movement (e.g., warm air rising in a room or ocean currents)
    • Radiation – heat transfer via electromagnetic waves (e.g., sunlight warming your skin or heat from a fire)

Who This Lesson Is For

This lesson is ideal for learners beginning their study of physics, students in engineering or environmental science, and anyone interested in how heat shapes our world.
