Which of the following thermodynamics principles or laws states that it is impossible to achieve absolute zero temperature in a finite number of steps?

💡 Solution & Explanation

The third law of thermodynamics asserts that the entropy of a pure crystalline substance approaches zero as the temperature approaches absolute zero, mathematically implying that absolute zero cannot be reached through any finite sequence of cooling processes. The first law addresses energy conservation, while the second governs entropy increase. Thermodynamic laws are core concepts in physics syllabi for competitive tests.
