Question

Gavin doesn't like stepping on the cold stone floor of his room on winter mornings. He isusually 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?A. What is the specific heat of carpet?B. Cold radiates out of the stone floor.C. Stone is a better thermal conductor than rugs.D. The stone floor feels colder than the carpet does.

Answer 1

In order to answer this question, let's go through all of the four options

A. What is the specific heat of carpet?

- This is not a good hypothesis because it is already posed as a question, not a feasible solution (what a hypothesis should be)

B. Cold radiates out of the stone floor.

- This is not a good hypothesis because it is hard to quantify this. The cold can radiate technically out of anything

C. Stone is a better thermal conductor than rugs.

- This is a good hypothesis because this statement can be tested and then proved false or correct.

D. The stone floor feels colder than the carpet does.

- This is not a good hypothesis since this is an opinion more than a statement

The correct answer is C
