Which is the BEST conclusion Calvin can draw based on the results of his investigation?
Understand the Problem
The question is asking for the best conclusion Calvin can draw from his investigation on how heat is transferred in materials, based on the observations he made during the experiment.
Answer
Heat transferred by conduction from water to fork.
The best conclusion Calvin can draw is that the heated water molecules collided with the fork, causing the heat to be transferred by conduction.
Answer for screen readers
The best conclusion Calvin can draw is that the heated water molecules collided with the fork, causing the heat to be transferred by conduction.
More Information
Conduction occurs when heat is transferred via direct contact between molecules, as seen in the experiment where the fork in hot water heated up.
Tips
A common mistake is confusing conduction with convection or radiation. Conduction involves direct contact, whereas convection involves fluid movement and radiation doesn’t require a medium.
