The energy supplied during latent heat is used to break/weaken intermolecular bonds and NOT to increase the kinetic energy of the molecules.

Latent heat is the energy absorbed or released during a phase change without a corresponding change in temperature. At the molecular level, this energy is used to break or form intermolecular bonds, such as when a substance changes from a solid to a liquid or a liquid to a gas. The kinetic energy of the molecules remains constant during a phase change, leading to a temporary "hidden" energy storage in the form of potential energy within the bonds.

What is Latent heat of fusion dependent?
The latent heat of fusion is dependent on the substance undergoing the phase change from solid to liquid. It is influenced by the specific properties of the material, such as its molecular structure and intermolecular forces. The amount of energy required to overcome these forces and convert the substance from a solid to a liquid state determines the value of the latent heat of fusion.
What are the factors that affect specific latent heat of fusion of a substance?
The factors that affect the specific latent heat of fusion of a substance include the type of material, its molecular structure, and intermolecular forces. The purity of the substance and any impurities present can also affect the specific latent heat of fusion. Additionally, temperature and pressure can influence the specific latent heat of fusion as well.
What is the symbol for latent heat?
The symbol for latent heat is ( L ).
Latent heat in terms of molecular behavior?
Latent heat refers to the heat energy that is absorbed or released during a change in state of a substance, such as melting or vaporization, without a change in temperature. It is due to the energy required to break intermolecular forces when a substance changes phases, rather than increasing the kinetic energy of the molecules.
What is the opposite of latent heat?
The opposite of latent heat is sensible heat. Sensible heat is the heat that causes a change in temperature of a substance without a change in phase.
How latent heat is an important source of atmospheric energy?
In the atmosphere latent heat is a property of water vapour. When water vapour condenses it releases latent heat, and latent heat must be supplied to evaporate liquid water. This heat affects the behaviour of the weather. Similar effects occur in the change from liquid water to ice and vice versa.
Why is latent heat of vapourisation higher than latent heat of fusion?
The latent heat of vaporization is higher than the latent heat of fusion because it takes more energy to change a substance from a liquid to a gas (vapor) than from a solid to a liquid. This is because breaking the inter-molecular forces in a liquid requires more energy than overcoming the intermolecular forces in a solid.
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.
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.
What is the heat that is released when water condenses and changes to liquid form?
The latent heat of vaporisation.
Latent heat in terms of molecular behavior?
Latent heat refers to the heat energy that is absorbed or released during a change in state of a substance, such as melting or vaporization, without a change in temperature. It is due to the energy required to break intermolecular forces when a substance changes phases, rather than increasing the kinetic energy of the molecules.
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 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 are the applications of latent heat of fusion and latent heat of vapourisation?
The latent heat of fusion is the amount of heat required to change a substance from solid to liquid at its melting point, while the latent heat of vaporization is the amount of heat required to change a substance from liquid to gas at its boiling point. These concepts are important in processes like melting and boiling of substances, refrigeration, and even in weather phenomena like cloud formation and rain.
What is the electrical method to determine the specific latent heat of vaporisation?
coclude the specific latent heat of vaporization
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.
