In what direction does heat flow?

Explanation:
Heat transfer is driven by temperature difference: energy moves from the warmer object to the cooler one until both reach the same temperature. The direction is determined by which object is hotter, not by how it looks. Color can affect how quickly heat is absorbed or emitted, so it can change the rate, but not the direction. This rule applies across conduction, convection, and radiation: energy flows to reduce the temperature gap. For example, a hot cup of coffee loses heat to the surrounding air and the cooler mug it sits in, until they’re all at the same temperature.
