Flows from hotter object to cooler object
WebSep 6, 2024 · Heat always travels from a warmer object to a cooler object. However, this process is not instantaneous. It takes time for the heat to flow from the warmer object to the cooler object. The amount of time it takes for the heat to flow from one object to another depends on the materials involved and the temperature difference between the two … WebAnswer (1 of 21): There is both a mathematical and theoretical explanation for this.
