What is the SI unit for latent heat of fusion?

The value of latent heat of fusion of ice is 3.36×105JKg−1 in S.I. unit of system. The specific latent heat of vaporization of the system is the heat energy needed to change one kilogram of the material in its liquid state at its boiling point to one kilogram of the material in its gaseous state.

What is latent heat its unit?

Answer: The unit of latent heat is joule. Latent heat is the amount of heat energy consumed or emitted during a phase change. The concept of latent heat was first introduced by a British chemist Joseph Black.

What are the units for heat of fusion?

The heat of fusion has units of J/g.

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 are two types of latent heat?

Two common forms of latent heat are latent heat of fusion (melting) and latent heat of vaporization (boiling).

What are three types of latent heat?

There are three different types of latent heats, Latent Heat of Fusion, Latent Heat of Vaporization, Latent Heat of Sublimation.

What is the symbol for heat of fusion?

\Delta H_f
We denote the Heat of fusion by the symbol \Delta H_f. When a solid material turns into the liquid, then it is what we know as melting.

What is the symbol for heat?

Q
The conventional symbol used to represent the amount of heat transferred in a thermodynamic process is Q. As an amount of energy (being transferred), the SI unit of heat is the joule (J).

What is latent heat give example?

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 formula for latent heat of fusion?

Equation of Latent Heat of Fusion. The equation for H f is as follows: H f =ΔQ f/ m. Here, ΔQ fis the change in the energy of the substance and m is the mass of the substance.

How do you calculate latent heat?

Latent heat calculation. All we need to know to compute the latent heat is the amount of substance and its specific latent heat. The formula is: Q = m * L, where. m [kg] is the mass of the body, L [kJ/kg] is the specific latent heat, Q [J] is the heat absorbed or released depending on the direction of the transition.

What unit is used to measure latent heat?

The specific latent heat (L) of a material… is a measure of the heat energy (Q) per mass (m) released or absorbed during a phase change. is defined through the formula Q = mL. is often just called the “latent heat” of the material. uses the SI unit joule per kilogram [J/kg].

What is the formula of latent heat?

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.
