Lesson Overview
Heat energy moves from warmer areas to cooler areas via conduction, convection, and radiation. This lesson covers the working principles of conduction through solids and convection within fluids in domestic plumbing systems.
Learning Objectives
Explain the molecular mechanism and rates of thermal conduction through common plumbing materials.
Describe how fluid density changes create convection currents in water and air.
Identify the practical applications of conduction and convection in heat exchangers, gravity circulation, and radiators.
