What is the direction of the energy flow between solids and liquids?

The direction of energy flow between solids and liquids typically occurs from the solid to the liquid. When a solid is heated, it transfers energy to the surrounding liquid, increasing the liquid's temperature and potentially causing it to change phase (e.g., melting ice into water). Conversely, if a solid is placed in a cooler liquid, energy may flow from the liquid to the solid, resulting in a decrease in the liquid's temperature. This energy transfer is governed by the temperature difference between the two phases.
