A student with a body temperature of 37°C holds a can of cold soda with a temperature of 18°C. The student is in a room with an air temperature of 22°C. 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 air to the can and the student.
Heat will flow from the air to the can and the student.
Heat will flow from the student to the can.
The correct answer is:
Heat will flow from the student to the can and the air, and from the air to the can.
The correct statement is:
Heat will flow from the student to the can and the air, and from the air to the can.
The correct statement is: "Heat will flow from the student to the can and the air, and from the air to the can."
To understand why this is the correct answer, we need to consider the temperature difference between the objects in the system. The student has a body temperature of 37°C, which is higher than the temperature of the can (18°C) and the air (22°C).
According to the second law of thermodynamics, heat always flows from objects with higher temperature to objects with lower temperature. Since the student is warmer than both the can and the air, heat will flow from the student to both of them.
However, the air is also warmer than the can, so heat will also flow from the air to the can. This is because the can is colder than the air, and heat will naturally move from the warmer air to the colder can to establish thermal equilibrium.
Therefore, heat will flow from the student to the can and the air, and from the air to the can.
