Understanding the Third Law of Thermodynamics - High School Physics

Card 0 of 1

Question

An object can never reach absolute zero in a finite number of steps. Which of these laws supports this statement?

Answer

The third law of thermodynamics states that it is impossible to decrease the temperature of a system to absolute zero in a finite number of steps. To do so would require that the entropy of the system also reaches zero, suggesting that the atoms cease vibrating in the material and it has zero net energy. Such a process is not possible.
