Question

This alligator is cold blooded. When it is cold, the alligator looks for a warm place to lay, like on the sand or a rock warmed by the sun. How does the sand or the rock warm the alligator? A) direct contact or conduction B) through the air or radiation C) by heating up the air around the alligator D) by transferring heat into the alligators blood

Answer 1

a) By direct contact or conduction

Answer 2

The right answer is A.

- Thermal conduction is specific to solids (such as soil, rock, wood, metals, etc.), it is a direct transfer within a material medium, which is done by spreading from near to heat. The thermal agitation motion (heat flow) always goes from hot areas (rock or sand) to cold areas (the alligator).
