What does latent heat of evaporation represent?
The latent heat of evaporation represents the amount of energy required to change a substance from liquid to gas at its boiling point without changing its temperature. This energy is used to overcome the intermolecular forces holding the molecules together in the liquid state.
Can latent heat be zero?
No, latent heat cannot be zero because it represents the heat energy absorbed or released during a phase change of a substance, such as melting, freezing, evaporation, or condensation. This energy is required to break intermolecular bonds or create them, so it cannot be zero.
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
What is called the release of latent heat along from water molecules on a wet surface?
The release of latent heat from water molecules occurs during the process of evaporation from a wet surface. This latent heat is absorbed by the water molecules to break intermolecular bonds, allowing them to transition from liquid to vapor state.
Is it true the rates of evaporation and condensation are equal at equilibrium?
Yes, at equilibrium the rates of evaporation and condensation are equal. This means that the liquid and gas phases reach a balance where molecules are transitioning between the two states at an equal rate.
What is latent heat evaporation?
Latent heat of evaporation of water to steam is 2270 KJ/Kg
What is the heat stored in the atmosphere as a result of evaporation?
Latent
What is heat called that is stored in the atmosphere as a result of evaporation?
the answer is latent Latent heat is correct, but specifically the latent heat of evaporation of (whatever is evaporated, in this case water) water. When the evaporated water condenses, it releases this latent heat as it precipitates, which is why it tends to feel warmer during rainstorms (unless the water is running down your neck in which case it feels horrible).
What does the body depend upon when cooling itself in a hot environment?
The latent heat of evaporation of water - the evaporation of sweat.
How does specific latent heat of water vary with temperature?
Latent heat of water is the heat required to change its state at a particular temperature BECAUSE of the pressure at which the water is at at the point of fusion or evaporation.The latent heat is not affected by temperature (in fact there is no temperature change during absorption of latent heat) it is affected by the pressure acting on a substance. As the pressure increases, the latent heat (of evaporation) decreases, consequently with the change in pressure there is also a different temperature at which the evaporation takes effect, higher pressure, higher temperature at the evaporation point.
The form of energy related to the change of the state of water?
The energy which must be transferred to or from a sample of water in order to change it's state is called the Latent Energy or Latent Heat - for example Latent Heat of Evaporation or Latent Heat of Freezing.
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 does latent heat of evaporation represent?
The latent heat of evaporation represents the amount of energy required to change a substance from liquid to gas at its boiling point without changing its temperature. This energy is used to overcome the intermolecular forces holding the molecules together in the liquid state.
Which occours when a liquid becomes a gas?
What do you mean? It's evaporation... The liquid absorbs latent heat from the surrounding...
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.
Is evaporating a physical change?
Yes. Evaporation is a physical change of state. In the case of evaporation enough heat, called the Latent Heat of Vaporization, is added to a liquid to change it from liquid to gas.
Is dimension for latent heat and gravitional pull equal?
s
