Neumann's principle
Neumann's principle, often related to heat transfer, states that the rate of heat flow into or out of a body is proportional to the temperature difference between that body and its surroundings. In simpler terms, the greater the temperature difference, the faster heat will move. This principle helps explain everyday phenomena, like why ice melts quicker in warm water than in a cool room. It's a fundamental concept in thermodynamics, influencing areas like engineering, climate studies, and even cooking. Essentially, it highlights how temperature differences drive energy transfer.
