Four Laws That Drive The Universe By Peter Atkins -.pdf-

The was represented by a series of interconnected pools of water, each at a different temperature. Maria realized that the pools were in thermal equilibrium with each other, illustrating how temperature was a fundamental property of the universe.

The third law, also known as the "Nernst-Simon statement", states that as the temperature of a system approaches absolute zero, the entropy of the system approaches a minimum value. Four Laws That Drive The Universe By Peter Atkins -.PDF-

As you cool a substance, you remove energy and lower its entropy. As you approach absolute zero (-273.15°C), molecular motion stops. However, Atkins explains via statistical mechanics that it would take an infinite number of steps to actually reach zero. You can get infinitely close—nanokelvins in a lab—but you can never cross the finish line. The was represented by a series of interconnected

Why does a hot coffee cool down? Because the energy wants to spread from the hot cup to the cooler room. Why can't we un-scramble an egg? Because that would require energy to concentrate, which would decrease entropy, which is statistically impossible. As you cool a substance, you remove energy
