Latent Heat of Evaporation, or Evaporation Enthalpy. It is given in units of energy
over unit of mass, i.e., KJ/Kg.
This energy is called enthalpy (or heat) of vaporization.
Heat of vaporization
the boiling point
The latent heat of vaporisation.
The atomic change that produces the largest amount of energy is a nuclear atomic change. This is when an atom is hit with another elementary particles and releases a large amount of energy.
No. Going from solid to liquid at constant temperature is an endothermic process. The required amount of energy is called "heat of fusion" of the material that changes state.
mass.
specific heat capacity
The heat energy required to change a substance between solid & liquid at constant temperature is called the "latent heat of fusion". If the change is from solid to liquid the substance gains this energy. If the change is from liquid to solid the substance gives up this energy. The exact amount of latent heat of fusion is different for different substances.
Heat capacity is the amount of heat energy required to raise the temperature of a unit mass of a material one degree.
Yes. Specific heat capacity is the amount of heat energy required to change the temperature of the material, so a material with high specific heat needs a lot of heat energy for its temperature to go up.
Heat of fusion.
It is the amount of energy required to change the state of 1kg of a substance with no change in temperature.
It is the amount of energy required to change 1kg of solid into a liquid with no temperature change.
The same amount of energy that is required to change it from a solid to a liquid. About 334.0 kJ/kg.
Specific heat
activation energy
Is the amount of energy required to change 1kg of liquid into gas with no temperature change.
The heat of fusion, also known as the enthalpy of fusion is how much energy is required to melt a solid to a liquid. This is the energy required to change the phase of the material - not the temperature. In fact at the melting point the heat capacity becomes infinite because all the energy is being used to change state and not temperature.As energy cannot be created or destroyed it is reasonable to assume it is the same amount of energy for a liquid to turn into a solid, which it is.So if energy is needed to change the phase of ice into water, the same amount of energy is released when water changes back into ice.
The latent heat of vaporization
The heat of fusion is the amount of energy required to change 1 unit mass of a solid to a liquid at constant temperature.
