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 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.
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).
Amount of heat necessary to change the state of substance?
Heat of vaporization or enthalpy of vaporization. It is the additional energy, per unit mass, required after vaporization temperature (boiling point) is reached, to accomplish the change in state, from liquid to gas.
What is relation between heat capacity and specific heat capacity?
The "specific heat capacity" is simply the heat capacity per unit - it might be per mass unit, per volume unit, or per amount of moles.
What unit is specific heat measured in?
In SI, specific heat capacity is measured in joules per kilogram kelvin.
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.
Correct units to determine specific heat?
Specific heat is the heat required to raise the temperature of a unit mass by one degree. It is measured by joules.
Is heat energy measured in units of joules degrees Celsius and in degrees Fahrenheit?
Heat is measured in unit of what...

What is a valid unit for specific heat?
Joule/kilogram-kelvin The SI unit is joules / kelvin. This is valid for an object of any size, but if you want the typical specific heat for a certain type of material, you have to standardize it, resulting in either joules / (kelvin x kilogram) or joules / (kelvin x mole).
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 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
Amount of heat necessary to change the state of substance?
Heat of vaporization or enthalpy of vaporization. It is the additional energy, per unit mass, required after vaporization temperature (boiling point) is reached, to accomplish the change in state, from liquid to gas.
What is the difference in crystallization and melting in Geology?
They're the same. latent heat of fusion - heat absorbed by a unit mass of a solid at its melting point in order to convert the solid into a liquid at the same temperature latent heat of solidification - heat liberated by a unit mass of liquid at its freezing point when it solidifies
What is heat measured of?
Enthalpy is the measurement of heat, Joule (J) is the unit. Temperature is not a measurement of heat. Temperature has the unit Kelvin (K) or Celsius (oC)
What late heat mean in HVAC?
All pure substances in nature are able to change their state. Solids can become liquids (ice to water) and liquids can become gases (water to vapor) but changes such as these require the addition or removal of heat. The heat that causes these changes is called latent heat. Latent heat however, does not affect the temperature of a substance - for example, water remains at 100°C while boiling. The heat added to keep the water boiling is latent heat. Heat that causes a change of state with no change in temperature is called latent heat. Appreciating this difference is fundamental to understanding why refrigerant is used in cooling systems. It also explains why the terms 'total capacity' (sensible & latent heat) and 'sensible capacity' are used to define a unit's cooling capacity. During the cooling cycling, condensation forms within the unit due to the removal of latent heat from the air. Sensible capacity is the capacity required to lower the temperature and latent capacity is the capacity to remove the moisture from the air.
