Latent Heat
Latent heat, a fundamental concept in thermodynamics, refers to the energy absorbed or released by a substance during a phase change without a corresponding change in temperature. This phenomenon plays a crucial role in various natural and industrial processes, including melting, freezing, vaporization, and condensation. Understanding latent heat is essential for explaining the behavior of matter undergoing phase transitions and is integral to fields such as meteorology, engineering, and materials science. In this introduction, we will delve into the principles underlying latent heat, its significance in different contexts, and its practical applications in diverse scientific and technological domains.
