Heat Transfer

---

• Thermal Contact is when two substances can affect each other's temperature.
• Thermal Equilibrium is when two substances in thermal contact no longer transfer heat.
• Thermal Expansion takes place when a substance expands in volume as it gains heat. Thermal contraction also exists.
• Conduction is when heat flows through a heated solid.
• Convection is when heated particles transfer heat to another substance, such as cooking something in boiling water.
• Radiation is when heat is transferred through electromagnetic waves, such as from the sun.
• Insulation is when a low-conducting material is used to prevent heat transfer.
