What requires more energy the latent heat vaporisation of water or the latent fusion of ice?
The latent heat of vaporisation of water requires more energy. This is because on melting, the intermolecular bonds in water are only weakened whereas on boiling, the bonds are completely broken, which requires a larger amount of energy.
When water at F boils it is only absorbing latent heat?
The water has already reached the 212 degree boiling point. At 212 degrees the water can exist as either a liquid or a vapor. Absorbing the latent heat pushes liquid to the vapor state without any change in temperature.
What is the heat that is released when water condenses and changes to liquid form?
The latent heat of vaporisation.
What is the latent of vaporization?
The latent heat of vaporization is what is commonly referred to as boiling. This is the amount of energy require to change from a state of liquid to vapor.
How much calories is needed to evaporate water?
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.
Why is the latent heat of vapourization of steam is more than that of boiling water?
Because steam is hotter than boiling water.
Why temperature does not rise even if water is heated as its boiling point?
In this first heat boil the water at its boiling point that is 100 degree Celsius, when the temperature is reached then heat supplied to water not boils the water it is used to change the state of the matter means heat is used to overcome the forces of attraction to change its state and the heat is latent heat of vaporisation.so this is latent heat (hidden heat) which not increase the temperature for some time.
Why Water is poured to extinguish burning wood?
The water takes heat in the form of latent heat at its boiling point to convert into vapour. this puts the fire down.
What requires more energy the latent heat vaporisation of water or the latent fusion of ice?
The latent heat of vaporisation of water requires more energy. This is because on melting, the intermolecular bonds in water are only weakened whereas on boiling, the bonds are completely broken, which requires a larger amount of energy.
Why in ice cube at 0 degree Celsius is much effective in cooling a drink that the same mass of water at 0 degree Celsius what is the formula?
Latent heat of the ice, liquid water has no latent heat reserves. Perhaps at freezing we should call it "latent cold" but thermodynamics has always referred to it as latent heat whether at boiling or freezing. +++ It is latent heat because the water (liquid or ice) at freezing-point (0ºC) still contains heat energy as its temperature is at about 217ºK.
Why does steam give you more burns that water?
steam is the gaseous transformation that takes place on heating water to its boiling point.Steam will give you more burn than the water boiling at 100 c as it has the latent heat of vapourisation in addition to the heat of fusion.Basically it has more heat content in the steam state than boiling water state.
Why does the temperature stops rising during melting and boiling point?
Because the latent heat of fusion and latent heat of vaporization are very high
Is heat lost during evaporation?
Not exactly.If you are boiling water then the temperature of the water reaches boiling point and stays there despite the fact that you are still applying heat to the pan (thus heat is going somewhere but not into the water!).What is happening is that the heat goes into the water vapour as it boils off / evaporates so it is not lost. This heat is called "latent heat".You get this latent heat back when the water vapour re-condenses into water and this property of being able to move heat in vapour phases is how fridges and heat pumps work and is the source of energy for hurricanes.
Amount of heat used to change from one state to another?
Known to be the latent heat of evaporation or latent heat of fusion in case of boiling and in case of freezing respectively.
What is the difference between latent heat and heat?
Usually as we give heat to a system then temperature of the system would rise. But at the boiling point though we give enormous amount of heat the temperature would remain the same and so the heat given is said to be latent and it is used to change water from liquid state to gaseous state. Hence the name latent heat
Why is latent heat important to the atmosphere?
Latent heat is an important form of atmospheric energy. Latent heat is a property of water vapor in the atmosphere and when water vapor condenses it releases latent heat. Latent heat must be supplied to evaporate liquid water and this heat affects the behavior of the weather.
