Why energy always moves from the warm to the cold
In short: Explore the fundamental principles governing every energy exchange in our universe, from heat flow to the concept of entropy.
This video examines the first and second laws of thermodynamics. The first law dictates that energy is conserved; any change in a system's energy must be balanced by an equal and opposite change in its surroundings. The second law introduces entropy, a measure of how energy is distributed. It explains why heat naturally flows from warmer objects to cooler ones until thermal equilibrium is reached, and why entropy cannot spontaneously decrease.
