What is latent heat of fusion of a solid?
It is the amount of heat (measured in the proper unit, say calories) required to change a unit mass (measured in the proper units, say gram) of a substance from the solid to the liquid state. This would also be the heat given out by a unit mass of the liquid when it changes to the solid state.
What is the dimensional formula of latent heat and specific heat?
The dimensional formula of latent heat is [L^2 T^-2], which signifies energy per unit mass. The dimensional formula of specific heat is [L^2 T^-2 K^-1], representing the amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius.
What is the specific latent heat of fusion of mercury?
The specific latent heat of fusion of mercury is about 11.28 kJ/kg. This value represents the amount of energy required to change a unit mass of solid mercury at its melting point to liquid mercury at the same temperature, without changing its temperature.
Can heat be measured in degrees Fahrenheit?
No, Fahrenheit is the Imperial Unit for temperature, not heat. Heat is energy in transit and is measured in joules (in the SI sytem).
What is the difference of heat capacity and latent heat?
Specific heat capacity (equation Q=mc��T) is the measure of the energy required in Joules to raise 1kg of a substance by 1.0 K (numerically equivalent to 1 C)Whereas, specific latent heat (equation Q=mL) is the amount of energy needed to change to the state of a substance either from solid to liquid, liquid to gas without changing its temperature.
What unit is specific heat measured in?
In SI, specific heat capacity is measured in joules per kilogram kelvin.

What does the latent heat of fusion measured?
The energy required to melt a substance
What is dimension of enthalpy?
The correct dimensional formula of latent heat is MoL2T2.
Can heat be measured in degrees Fahrenheit?

Specific heat is measured in?
Specific heat is measured in units of energy per unit mass per degree Celsius (J/kg°C or cal/g°C). It indicates the amount of heat energy required to raise the temperature of a specific amount of a substance by one degree Celsius.
Is latent heat of vaporisation fixed?
No, the latent heat of vaporization is not fixed and can vary depending on the substance. It represents the amount of energy required to change a unit mass of a substance from liquid to gas at a constant temperature and pressure.
What is SI unit of latent heat of fusion?
The latent heat of fusion is defined as the heat energy required to convert a kg of a substance of liquid into solid of the same substance without a change of temperature. Q = mL where Q = Heat Energy in joules, m=mass of substance, L= Latent heat of fusion Taking units, [J] = [kg] [L] [L] = [J]/[kg] so units of latent heat of fusion are joules.kg-1
What is the quantity of heat required to raise unit mass?
The quantity of heat required to raise the temperature of a unit mass of a substance by one degree Celsius is known as specific heat capacity. It is a constant value for each substance and is measured in J/kg°C.
