Latent heat is energy either lost or gained by a substance when it changes state. Measured in energy, latent heat is caused by...
What is latent heat ? Write its unit and dimensional formula. 03:42 On what does the value of latent heat depend ? 00:46 What is latent heat of fusion ? Give its value for water. 02:22 What is latent heat of vaporization ? 02:56 What is heat transfer ? Write its modes. 01:14 ...
While latent heat of fusion and vaporization are used in physics and chemistry, meteorologists also consider sensible heat. When latent heat is absorbed or released, it produces instability in the atmosphere, potentially producing severe weather. The change in latent heat alters the temperature of obj...
What is latent heat? Latent heat, on the other hand, is the heat required to change the state of a substance without changing its temperature. All pure substances in nature can change their state; solids can become liquids (ice to water) and liquids can become gases (water to vapor). Th...
So what, exactly, is latent heat? I am given to understand that the energy is stored in the molecule in the form of changes to bond angles. With water, the bond angle between the hydrogen atoms changes by a degree or so during melting. Here, the bond angle is described as well as ...
What is the dimensional formula of latent heat?HeatThere are two types of heat namely sensible heat and latent heat. The heat responsible for change in temperature of the body at constant phase is called sensible heat. The heat responsible for change in phase at constant temperature is called ...

What is thermal evaporation? What additive lowers the glass transition temperature of tire rubber? What is latent heat of evaporation? What is the latent heat of fusion for ice? What phase change is evaporation? What does temperature measure?
Heat flux due to temperature differences is called sensible heat flux as opposed to latent heat flux, which refers to the flow of heat due to phase changes in the medium. Critical heat flux is the amount of heat that can be pumped through a given surface in a given amount of time, in...
