What are the latent heat and sensible heat of steam and what is the difference?
The heat absorbed or released when unit mass of steam increases or decreases by 1°C (still maintains steam state) is the sensible heat at that temperature.； At a certain temperature, the heat released when all unit mass of steam is condensed into liquid at the same temperature is the latent heat at that temperature.
sensible heat: When a solid, liquid or gaseous substance is heated, as long as its form remains unchanged, the temperature of the substance will rise after heat is added. The amount of heat added can be displayed on the temperature, that is, the heat that does not change the shape of the substance but causes its temperature to change is called sensible heat. latent heat: For example, when liquid water is heated, the temperature of the water rises. When it reaches the boiling point, although heat is continuously added, the temperature of the water does not rise and stays at the boiling point. The added heat only changes the water into water vapor, that is, from liquid to gas. This kind of heat that does not change the temperature of a substance but causes a change in the state of matter (also called a phase change) is called latent heat. The heat absorbed by 1Kg of liquid completely turning into saturated vapor at the same temperature is called the latent heat of vaporization at that temperature, represented by the symbol r in units of kJ/kg.
Sensible heat is the unit heat when there is no phase change, and latent heat is the unit heat when there is a phase change.
The difference is whether there is a phase change. . . . . . . .

Sensible heat is the unit heat when there is no phase change, and latent heat is the unit heat when there is a phase change.
