What is the flow that transfers heat within a fluid? A constant flow begins. Cooler, denser soup sinks to the bottom of the pot. Simultaneously, warmer, less dense soup rises. What is the flow that transfers heat within a fluid?
Convection Current
What is the transfer of energy that is carried in rays such as sunlight?
Radiation
How is your body experiencing heat transfer right now?
