Transcript text: The primary mode of energy transfer when you use a heating blanket to get warm is conduction convection radiation

Solution

Solution Steps

Step 1: Identify the Mode of Energy Transfer

When using a heating blanket, the primary mode of energy transfer is through direct contact between the blanket and the body. This involves the transfer of heat from the warmer object (the heating blanket) to the cooler object (the person) through direct contact.

Step 2: Determine the Appropriate Mode

The three modes of heat transfer are conduction, convection, and radiation. Conduction occurs when heat is transferred through direct contact between materials. Convection involves the movement of heat through fluids (liquids or gases), and radiation involves the transfer of heat through electromagnetic waves without the need for a medium.

Step 3: Select the Correct Answer

Since the heating blanket transfers heat through direct contact with the body, the primary mode of energy transfer is conduction.
