Question

Ms. Gordon's class is studying radiation. They covered plastic cups with black construction paper or white construction paper. They filed the cups with water that was C. They placed the cups of water in the sun and recorded the temperature of the water every 15 minutes. The student data can be seen in the graph above.

Mary and Alice were collecting the data for the class. Both girls were wearing white T-shirts. Billy came out to help them; he was wearing a dark navy T-shirt. "Boy, it is really hot out here," exclaimed Billy. The girls said they were not hot at all. Using the student experiment and the collected data, elaborate on the reason for the students' comments.

The best response to elaborate on the students' comments based on the context of the experiment studying the effects of radiation is:

**A. White T-shirts reflect sunlight. Black T-shirts do not.**

This explains why Billy felt hotter in his dark navy T-shirt compared to Mary and Alice, who were wearing white T-shirts. Darker colors absorb more sunlight and heat, while lighter colors reflect sunlight, leading to a cooler experience for those wearing them. The experiment with the cups covered in black and white construction paper aligns with this understanding of how color affects heat absorption and temperature.
