Question

n which scenarios does conduction occur? Check all that apply.

Ice cream is placed in a bowl chilled to the same temperature.
An ice pack is placed on a sprained ankle.
A piece of frozen fish is placed in a hot frying pan.
A metal pot is held 15 cm above a hot stove.
A lizard is lying on a warm rock.

Answer 1

Conduction occurs in:
- An ice pack placed on a sprained ankle.
- A piece of frozen fish placed in a hot frying pan.
- A lizard lying on a warm rock.

Reason: Conduction is heat transfer through direct contact and requires a temperature difference between the contacting surfaces. The ice pack/ankle, fish/pan, and lizard/rock meet both conditions.

The ice cream in a bowl at the same temperature has no net heat flow (no conduction). The metal pot held 15 cm above the stove is not in contact with the stove, so heat transfer would be by radiation/convection, not conduction.
