Question: What Is Latent Heat Of Fusion Short Answer?

What is L in latent heat?

Updated November 04, 2019.

Specific latent heat (L) is defined as the amount of thermal energy (heat, Q) that is absorbed or released when a body undergoes a constant-temperature process..

What is latent heat of fission?

The amount of heat energy exchanged per unit mass of a substance is called Latent Heat. Latent heat of fission is analogous to latent heat of fusion.

What is Latent Heat formula?

Answer: The latent heat is given by the equation: Q= m L. substituting the value of m, and the specific latent heat. Q= 0.5 Kg * 334 KJ/Kg = 167 KJ = 167000 J. This is the amount of energy released when water is melting at 0 °C.

What is the example of latent heat?

For example, when a pot of water is kept boiling, the temperature remains at 100 °C (212 °F) until the last drop evaporates, because all the heat being added to the liquid is absorbed as latent heat of vaporization and carried away by the escaping vapour molecules.

What is the difference between heat and latent heat?

Specific heat is the amount of heat required to raise the temperature of a substance a certain amount. Latent heat is the amount of heat released during a change of state, i.e. the boiling of water or the melting of ice.

What is the latent heat of water?

Changing of phase undergoes a heat transfer, but the temperature of the substances remains constant. So, the heat necessary for phase changes of water from solid to liquid or gas, or liquid to solid or gas, without any temperature alteration is known as latent heat of water.

What is latent heat and its types?

Latent heat is energy released or absorbed, by a body or a thermodynamic system, during a constant-temperature process. Two common forms of latent heat are latent heat of fusion (melting) and latent heat of vaporization (boiling).

What is the definition of latent heat of fusion?

The enthalpy of fusion of a substance, also known as (latent) heat of fusion is the change in its enthalpy resulting from providing energy, typically heat, to a specific quantity of the substance to change its state from a solid to a liquid, at constant pressure.

What is Latent Heat Class 9?

The latent heat of fusion or melting of solid is the quantity of heat in joules required to convert 1 kg of solid to liquid,without any change in temperature. … The heat which is going into ice but not increasing its temperature,is the energy required to change the state of ice from solid to liquid.

What is latent heat of fusion formula?

BSL Physics Glossary – specific latent heat of fusion – definition. Eh means energy, equals m for mass, times l. l is the specific latent heat of fusion for that material. So the formula tells us how much heat energy is needed to go into a material to change it from a solid to a melted liquid.

What is the latent heat of fusion answers com?

Answer: The latent Heat of Fusion is the change inenthalpy resulting from heating a given quantity of a substance to change its state from a solid to a liquid. The temperature at which this occurs is the melting point.

How do you get latent heat?

Latent Heat Of Fusion FormulaL = specific latent heat of fusion of substance.The total amount of heat absorbed or liberated by the material is.Let c be the specific heat of the metal.Heat gained by the metal.Q = 60 × c × (100 – 20)Q = 60 × c × 80 cal.Heat given is equal to Heat taken.0.5 × 540 = 60 × c ×80.

What is the latent heat of steam?

As the latent heat of steam at atmospheric pressure is 2257 kJ/kg the amount of flash steam produced will be 299/2257 = 0.133 kg/kg of condensate.

What is the dimension of latent heat?

Or, L = [M1 L2 T-2] × [M1 L0 T0]-1 = [M0 L2 T-2]. Therefore, latent heat is dimensionally represented as [M0 L2 T-2].
