Possible Points: 1
A student with a body temperature of 37oC holds a can of cold soda with a temperature of 18oC. The student is in a room with an air temperature of 22oC. Which statement best describes the flow of heat throughout the entire system?
Responses

Heat will flow from the student to the can and the air, and from the air to the can.
Heat will flow from the student to the can and the air, and from the air to the can.

Heat will flow from the student to the can and the air to the can.
Heat will flow from the student to the can and the air to the can.

Heat will flow from the student to the can.
Heat will flow from the student to the can.

Heat will flow from the air to the can and the student.

Answer 1

To understand the flow of heat in this scenario, we need to consider the temperatures of all entities involved: the student (37°C), the soda can (18°C), and the air (22°C).

1. **Heat Transfer Basics**: Heat flows from an object with a higher temperature to an object with a lower temperature.

2. **Analysis**:
- The student is at 37°C, which is higher than both the can (18°C) and the air (22°C).
- Therefore, heat will flow from the student to both the can and the air.
- The air is also at a higher temperature (22°C) than the can (18°C), so the air will transfer heat to the can as well.

Given these points, the correct statement that best describes the flow of heat throughout the entire system is:

**Heat will flow from the student to the can and the air, and from the air to the can.**
