As you touch a hot stove the heat transfers: from your hand to the stove from the stove to your hand it doesn't transfer 21. Convection could occur in which of the materials below? A block of wood The ocean A bowl of ice cream The vacuum of outer space 22. Which sentence explains why a cold metal spoon placed in a pot of boiling water becomes hot? Thermal energy is transferred by conduction from the spoon to the water Thermal energy in the spoon is transformed into kinetic energy in the water. Thermal energy in the water is transformed into kinetic energy in the spoon Thermal energy is transferred by conduction from the water to the spoon. 23. What evidence demonstrates that convection currents are at work? The sun transferring it's heat through outer space Smoke and heat rising from a lighted candle wick The handle of a pan on a stove gets hot Your face feels warm sitting beside a fire 24. ONLY radiation could occur through which of the materials below? (Think carefully!!) A block of wood The ocean A bowl of ice cream The vacuum of outer space 25.

How is some of the heat being transferred to the room? Up through the chimney and out of the house (convection) Through the air in every direction (radiation) Through direct contact with the metal (conduction) 27. How is the smoke from the burning wood leaving the room? Through direct contact with the metal (conduction) Through the air in every direction (radiation) Up through the chimney and out of the house (convection) 28. How is the teapot heating up? Up through the chimney and out of the house (convection) Through the air in every direction (radiation) Through direct contact with the metal (conduction) 29.
