In which of the following situations would convection currents most likely occur? a: within a block of iron that has been placed in a freezer b: within the water in a lake as ice forms on the top c: within a spoon that has been placed into warm soup d: within a plastic box from which all the air has been removed i think its c?

Option (B) is the correct answer.

Explanation:

Convection is defined as a process in which a fluid (liquid or gas) is heated and the cooler liquid (more dense) settles or sinks at the bottom whereas a hotter material (less dense) will rises to the top.

For example, ice being less dense (cooler material) will float in a lake whereas liquid water being more dense will sink at the bottom.

Thus, we can conclude that situation in which convection currents most likely occur is within the water in a lake as ice forms on the top.
