Which of the following describes the transfer of heat from one molecule to another?

The transfer of heat from one molecule to another is best described by conduction. This process occurs when heat is transferred through direct contact between molecules in solids, where energy is passed from one molecule to its neighboring molecule through vibrations or collisions. As the molecules at a higher temperature collide with those at a lower temperature, energy flows from the warmer to the cooler area, resulting in an increase in temperature of the cooler area.

Understanding conduction is fundamental in various applications, including insulating materials in building construction, where efficient heat transfer control is necessary to maintain comfortable indoor environments. In contrast, radiation involves the transfer of heat through electromagnetic waves, which doesn’t require direct contact, while convection refers to heat transfer through the movement of fluids (liquids or gases) due to differences in temperature and density. Evaporation, on the other hand, is the process of transition from liquid to gas, which also facilitates cooling but is not a direct means of heat transfer between molecules in a solid structure.
