What is the heat that is released when water condenses and changes to liquid form?
The latent heat of vaporisation.
What is the electrical method to determine the specific latent heat of vaporisation?
coclude the specific latent heat of vaporization
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.
What energy is required to create a phase change without changing the temperature?
It is called the latent heat of vaporisation.
Latent heat of vaporisation decreases as pressure increases and becomes zoro at critical pressure i read . why it so?
As pressure increases the temperature required to vaporize water is less. So with increase in pressure there is decrease in temperature required to boil so latent heat also decreases.
What is the heat that is released when water condenses and changes to liquid form?
The latent heat of vaporisation.
What is the electrical method to determine the specific latent heat of vaporisation?
coclude the specific latent heat of vaporization
What do you call the heat energy that is released or absorbed during a change of state of water?
latent heat of fusion, or of vaporisation or enthalpy of fusion, or of vaporisation Please see the link
Why do you feel cool after you perspire?
Because as water evaporates it absorbs latent heat of vaporisation
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 the time needed to vaporize a sample is greater than the time needed to melt a sample?
The amount of time depends on the latent heat of vaporisation and the latent heat of melting.
What energy is required to create a phase change without changing the temperature?
It is called the latent heat of vaporisation.
What is specific latent heat of vaporisation?
Is the amount of energy required to change 1kg of liquid into gas with no temperature change.
What is the name of the process in which liquid water turns into water vapour?
this process is called evaporation. it occurs when the bonds break, due to the average amount of energy, the temperature, going up enough to provide the latent heat of vaporisation. the latent heat of vaporisation is merely the name of the energy amount that it takes to break the bonds.
What is the amount of energy required to change a material from a liquid to a gas?
Latent Heat of Evaporation, or Evaporation Enthalpy. It is given in units of energy over unit of mass, i.e., KJ/Kg.
Define latent heat of fusion and latent heat of vapourisation?
Latent heat of vapourisation can be define as the rate by which water is heat to vapourise, it has a difference with evaporation because evaporation occurs directly when the water start heatin while vapourisation always start in a specific temperature
Latent heat of vaporisation decreases as pressure increases and becomes zoro at critical pressure i read . why it so?
As pressure increases the temperature required to vaporize water is less. So with increase in pressure there is decrease in temperature required to boil so latent heat also decreases.
