The transfer of heat from one molecule to another describes the process of ___________.

The correct answer is conduction. This process involves the transfer of heat through direct contact between molecules. When heat is applied to one part of a material, the molecules in that area begin to vibrate and transfer energy to adjacent molecules, resulting in an increase in heat in those areas as well. This transfer occurs without any movement of the material as a whole.

In the context of attic ventilation and insulation, understanding conduction is essential because it illustrates how heat can be lost or gained in a building. Insulators function by limiting the transfer of heat through conduction, helping maintain the desired indoor temperature. This knowledge is crucial for evaluating the effectiveness of insulation materials and ensuring that energy loss through conduction is minimized.
