Specific Heat vs. Latent Heat: What's the Difference?

Edited by Sara Rehman || By Sumera Saeed || Published on December 3, 2023
Specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius, while latent heat is the heat absorbed or released during a phase change of a substance, without changing its temperature.

Key Differences

Specific Heat refers to the quantity of heat required to change the temperature of a unit mass of a substance by one degree Celsius. It is a measure of a material's ability to absorb heat energy. Latent Heat, on the other hand, is the amount of heat absorbed or released by a substance during a phase change, such as melting or boiling, without any change in temperature.

Latent Heat is crucial in understanding phase changes, like ice melting to water or water evaporating to vapor, where the temperature remains constant despite heat exchange. Specific Heat is more concerned with the thermal capacity of a substance during temperature changes not involving phase transitions.

In the context of Specific Heat, different substances require different amounts of heat energy to achieve the same temperature change, reflecting their unique thermal properties. Latent Heat represents the hidden energy involved in altering the state of a substance, like solid to liquid or liquid to gas, without temperature variance.

Specific Heat is a fundamental concept in thermodynamics, playing a pivotal role in heat transfer and temperature regulation in various applications. In contrast, Latent Heat is key in processes involving phase transitions, significantly impacting climatic, industrial, and environmental systems.

The study of Latent Heat provides insights into the energy required for phase changes, essential in meteorology, refrigeration, and heating systems. Specific Heat, however, is integral in designing materials and systems for efficient heat absorption and release, essential in engineering and environmental management.
