Item NG033004: A girl feels warmer when she is in the sun than when she is under an umbrella in the shade because energy is being transferred directly from the sun to the girl.
A girl is sitting under an umbrella at the beach on a sunny day. Will she feel warmer if she moves out of the shade and into the sunlight? Why or why not?
- Yes, she will feel warmer in the sunlight because energy is being transferred directly from the sun to the girl.
- Yes, she will feel warmer in the sunlight but not because energy is being transferred directly from the sun to the girl. Energy is being transferred from the sun to the air and then from the air to the girl.

- No, she will not feel warmer in the sunlight because the air temperature in the sunlight is the same as the air temperature in the shade.
