You might take a known quantity of water, add heat and stir until all of it has reached
a temperature of 100 C (212 F), then start measuring how much more heat it takes to
turn all of the water to steam.
That's not exactly a 'derivation'. It's more like an empirical measurement, and we're thinking
that's how the figure was originally determined.

How is a steam burn an example of latent heat?
A steam burn is an example of latent heat, because beside the heat released by the steam itself, a part of it condenses, turning into water, which in turn releases heat too.
What is the energy released when steam condenses to water?
Latent heat of condensation.
What is the heat that is released when water condenses and changes to liquid form?
The latent heat of vaporisation.
What do you call heat that is added or removed from a substance but does not change the state of the substance sensible heat latent heat super heat or radiation heat?
Latent Heat.
What are the applications of latent heat of fusion and latent heat of vapourisation?
the application of latent heat fo fussion is ice is used to put in drinks to make cool because ice has hih specific heat capcity
What is latent heat evaporation?
Latent heat of evaporation of water to steam is 2270 KJ/Kg
How is a steam burn an example of latent heat?

Does steam has highest latent heat than boiling water?
Boiling water has a lower latent heat than steam. Steam is the transition from liquid to gas for boiling water. If by boiling water you mean liquid water at the temperature of 100 degrees Celsius then yes, steam has a higher latent heat.
Which contains more heat energy water at 373K or steam at 373K Why?
it is steam because it occupies latent heat of fusion ..............
What is the energy released when steam condenses to water?
Latent heat of condensation.
Why is the latent heat of vapourization of steam is more than that of boiling water?
Because steam is hotter than boiling water.
What happens to the energy of steam after it has been used in a powerstation?
after generating electricity its latent heat decreases
Difference between sensible heat and latent heat?
Sensible heat is heat supplied or taken away and causes an immediate change in temperature without changing the state. While latent heat is heat supplied or taken away and causes a change in state without change in temperature. This difference can be applied to the certain properties of water/steam. This is called the thermodynamics properties of steam.
What is the definition of the term 'latent heat'?
Latent heat is the amount of energy that is needed to change the state of matter. Either from a solid to a liquid, from a liquid to gas or vice versa. For example if you boil a kettle of water, energy or latent heat is added to the water from the element within the kettle. The water will heat up and eventually turn to steam.
How is steam created?
steam is created by the vapourisation of water (gaseous state of water is the steam). Steam is the result of a liquid changing to a gas. Liquid+heat=latent point of vaporization+additonal heat=steam. I could give you the delta change formula but lets use the kiss method
Can latent heat be zero?
No, latent heat can never be zero.Because latent heat is the hidden heat so there has to be heat more than zero.
Heat that causes a substance to change form is called?
latent heat :)
