what do you understand by the term latent heat of fusion
Answers
Answer:
The amount of heat gained by a solid object to convert it into a liquid without any further increase in the temperature is known as latent heat of fusion. The content of latent heat is complex in the case of sea ice because it is possible for sea ice and brine to exist together at any temperature and melt at a temperature other than 0oC when bathed in a concentrated salt solution, just like it occurs in the walls of brine cells when brine cells migration occurs. If m kg of solid converts to a fluid at a constant temperature that is its melting point, the heat consumed by the substance or the latent heat of fusion formula is expressed as
Q = m × L
Wherein
L = specific latent heat of fusion of substance.
The temperature of the substance changes from t1 (low temperature) to t2 (high temperature) the heat which the material absorbs or releases is expressed as
Q = mc Δt
Q = mc (t2 – t1)
The total amount of heat absorbed or liberated by the material is
Q = mL + mc Δt
The latent heat-related concept is marked below in the table
Explanation:
Answer:
The latent heat of fusion is the enthalpy change of any amount of substance when it melts. When the heat of fusion is referenced to a unit of mass, it is usually called the specific heat of fusion, while the molar heat of fusion refers to the enthalpy change per amount of substance in moles.
