What is the third law of thermodynamics?
The Third Law of Thermodynamics is the lesser known of the three major thermodynamic laws. Together, these laws help form the foundations of modern science. The laws of thermodynamics are absolute physical laws – everything in the observable universe is subject to them. Like time or gravity, nothing in the universe is exempt from these laws. In its simplest form, the Third Law of Thermodynamics relates the entropy (randomness) of matter to its absolute temperature. The Third Law of Thermodynamics refers to a state known as “absolute zero.” This is the bottom point on the Kelvin temperature scale. The Kelvin scale is absolute, meaning 0 Kelvin is mathematically the lowest possible temperature in the universe. This corresponds to about -273.15 Celsius, or -459.7 Fahrenheit. In actuality, no object or system can have a temperature of zero Kelvin, because of the Second Law of Thermodynamics. The Second Law, in part, implies that heat can never spontaneously move from a colder body to a hot
