What occurs during conduction between two solid objects?

During conduction between two solid objects, heat is transferred from the hotter object to the cooler one. This process occurs at the molecular level, where faster-moving (and thus hotter) molecules collide with slower-moving (and therefore cooler) molecules, transferring kinetic energy in the process.

The transfer continues until thermal equilibrium is reached, which is when both objects are at the same temperature. This mode of heat transfer is essential in many everyday situations, such as when touching a metal spoon that has been sitting in a hot pot of soup; the heat from the soup is conducted through the spoon to your hand.

In contrast, other options like heat being released to the environment, the production of gases, or electricity generation do not occur directly as a result of conduction between solid objects. These processes involve different physical mechanisms or conditions that are not characteristic of conductive heat transfer.
