Praxis 5005 Practice Question
A metal spoon that heats up while sitting in a bowl of hot soup is an example of heat transfer by:
Correct Answer: A
Rationale: Heat transfer occurs in various ways, and in this scenario, the metal spoon heats up through conduction. This process involves direct contact between the spoon and the hot soup, allowing thermal energy to transfer from the soup to the spoon.
Convection (Option B) refers to heat transfer through the movement of fluids, which does not apply here as the spoon is not moving the soup. Radiation (Option C) involves heat transfer through electromagnetic waves, which is not relevant in this context. Diffusion (Option D) is a process related to the movement of particles, not thermal energy transfer. Thus, conduction is the only applicable method in this situation.
