Energy: Forms, Transformation, Transfer, and Conservation
Item NG033003: A girl feels warmer when she is in the sunlight than when she is in the shade under an umbrella because energy is being transferred directly from the sun to the girl when she is in the sunlight.
A girl is sitting under an umbrella at the beach on a sunny day. When she moves out of the shade and into the sunlight, she will feel warmer. Why?
- Because energy is being transferred directly from the sun to the girl
- Because energy is being transferred from the sun to the air and then from the air to the girl, but no energy is being transferred directly from the sun to the girl
- Because energy is being transferred from the sun to the ground and then from the ground to the girl, but no energy is being transferred directly from the sun to the girl
- Because the sun is shining on the girl, not because energy was transferred from the sun to the girl
