Item NG102003: A person will feel cooler when she holds a blanket up between her and a campfire because the blanket is blocking the energy being radiated by the fire.
A girl is sitting by a campfire. She feels warm even though she is not touching the fire.
What will happen if the girl holds a blanket up so that the blanket is between herself and the fire but not touching her?
- She will feel warmer because blankets keep people warm.
- She will feel cooler because the blanket is blocking the energy radiated by the fire.
- She will feel the same because holding the blanket up will not change the temperature of the air outside.
- She will feel the same because she will still receive the same amount of energy from the fire even though the blanket is between herself and the fire.
