Specific Heat vs. Latent Heat — What's the Difference?
By Tayyaba Rehman — Published on October 13, 2023
Specific Heat is the amount of heat per unit mass required to raise the temperature of a substance by one degree Celsius, while Latent Heat is the heat absorbed or released during a phase change without changing temperature.

Key Differences
Specific Heat is a fundamental concept in thermodynamics and refers to the amount of heat per unit mass required to elevate the temperature of a substance by one degree Celsius or Kelvin. This property is crucial in determining how substances absorb and release heat. In contrast, Latent Heat is associated with the heat absorbed or released by a substance during a phase change, such as melting or boiling, with no change in temperature. It is pivotal in understanding the energy changes during phase transitions.
The measure of Specific Heat is indicative of a substance's ability to store heat and is extensively used to assess the thermal properties of materials. It essentially quantifies how much energy is needed to alter the temperature of a substance. On the other hand, Latent Heat provides insights into the energy required for a substance to change its state, reflecting the intrinsic properties of matter and their interaction with heat without altering the temperature.
In practical applications, Specific Heat is critical in designing thermal systems and materials, influencing how quickly objects heat up or cool down under thermal influence. Conversely, Latent Heat is fundamental in various processes such as refrigeration and climate science, depicting the energy interactions occurring during state changes of substances, without reflecting in the temperature scale.
The variability in Specific Heat among different materials underscores the diverse thermal behaviors exhibited by substances under heat exposure. Distinctly, Latent Heat emphasizes the inherent energy changes occurring within substances undergoing phase transformations, elucidating the concealed heat interactions not evident in temperature shifts.
