Gavin doesn't like stepping on the cold stone floor of his room on winter mornings. He is usually careful to walk on the rugs laid
over parts of the floor. One day, he wonders why the rugs feel warmer than the stone floor. Since the rugs sit on the bare floor all
the time, he thinks they should be at about the same temperature.
Which of the following is a good hypothesis Gavin can use to help satisfy his curiosity?
OA. Stone is a better thermal conductor than rugs.
OB. What is the specific heat of carpet?
OC. The stone floor feels colder than the carpet does.
