All require matter

3. Fill in the blanks:

When you touch a hot metal spoon, heat transfers through _______________. When you feel warm air rising from a heater, heat transfers through _______________. When you feel the sun's warmth on your face, heat transfers through _______________.

🌡️ Part 2: Real-World Examples

4. Identify the type of heat transfer in each scenario. Write C for Conduction, V for Convection, or R for Radiation:

_____ A metal spoon gets hot when left in a pot of boiling soup

_____ Feeling warmth from a campfire without touching it

_____ Hot air balloons rising because warm air is less dense

_____ Burning your hand on a hot car door handle

_____ Warm ocean currents moving around the globe
