define specific latent heat of vaporization
Question
define specific latent heat of vaporization
Solution
The specific latent heat of vaporization is a term used in thermodynamics to describe the amount of heat energy required to change one kilogram of a substance from a liquid state to a gaseous state without changing its temperature. This is a specific property of each substance and varies depending on the substance in question. It is usually measured in joules per kilogram (J/kg).
Here are the steps to define it:
-
Understand the concept of latent heat: Latent heat is the heat absorbed or released by a substance during a phase change (like from solid to liquid, liquid to gas, and vice versa) at constant temperature and pressure.
-
Differentiate between latent heat of fusion and vaporization: The latent heat of fusion is the heat absorbed or released when a substance changes from solid to liquid or vice versa. On the other hand, the latent heat of vaporization is the heat absorbed or released when a substance changes from liquid to gas or vice versa.
-
Define specific latent heat: The specific latent heat of a substance is the amount of heat energy required to change 1 kg of that substance from one state to another without changing its temperature.
-
Finally, define specific latent heat of vaporization: The specific latent heat of vaporization is the amount of heat energy required to change 1 kg of a substance from a liquid state to a gaseous state without changing its temperature.
