📖 Three Ways Heat Escapes

Your house is constantly losing heat — through the walls, roof, windows, and floor. But HOW does heat actually move? There are three different mechanisms: conduction (vibrating particles passing energy through solids), convection (hot fluid rising and cold fluid sinking), and radiation (infrared waves that don't need any particles at all). Understanding these helps explain everything from why metal spoons get hot to why the Sun can warm the Earth across 150 million km of empty space!
💡 Think of it like three ways to pass a ball...

Conduction is like passing hand-to-hand in a line — each person touches the next, energy passes along, but nobody moves from their spot. Convection is like a relay race — the carrier physically moves to deliver the energy. Radiation is like throwing the ball across an empty field — nothing in between, but energy still arrives at the destination!
