A student holds an ice cube in her hand. Which of the following BEST describes the movement of heat that will happen?
A
Heat will flow from her hand to the ice cube via radiation.
B
Cold will flow from the ice cube to her hand via conduction.
C
Cold will flow from the ice cube to her hand via convection.
D
Heat will flow from her hand to the ice cube via conduction.
D
Heat will flow from her hand to the ice cube via conduction.
D
Heat will flow from her hand to the ice cube via conduction.
To determine the correct answer, we need to understand the concepts of heat transfer. In this case, we have an ice cube (which is colder) being held by a student's hand (which is warmer). The direction of heat transfer will depend on the method of heat transfer involved.
Radiation is the transfer of heat through electromagnetic waves, such as light or infrared radiation. Conduction is the transfer of heat through direct contact between objects. Convection is the transfer of heat through the movement of a fluid (liquid or gas).
In this scenario, the student is holding the ice cube in her hand, and the heat will flow from her hand to the ice cube. This means that heat is transferring from a warmer object (her hand) to a colder object (the ice cube).
Therefore, the correct answer is D: Heat will flow from her hand to the ice cube via conduction.
