E.g. heat from the sun, or the red coals of a camp fire. We discussed three different versions of the 2 nd law of thermodynamics in class. State one of these versions. Heat will not flow spontaneously from a cool to a warm body You cannot construct an engine that does nothing but convert heat to useful work. Every isolated system becomes more disordered with time.
Every isolated system becomes more disordered with time.
The universe is winding down and ultimately will be a chaotic gas-like state at the same temperature everywhere. Name four ways to make a magnet. Describe Oerstad s experiment. He generated a current via a battery. He noticed, out of the corner of his eye, that the needle on a compass would flicker and change direction when the current flowed.
