Is heat of fusion physical or chemical property?
Heat of fusion is a physical property.
What chemical bond possess low latent heat of fusion?
Latent heat of fusion (or enthalpy of fusion) is a characteristic of a substance, rather than a chemical bond. If you mean enthalpy of reaction then the lowest absolute values are for the bonds in H2, F2, and Cl2 as gases, which are zero. One low (and negative) value is for cuprous sulphate. Please see the link.
The energy required to melt one gram of a substance is known as what?
heat of fusion
What specific heat is the energy used to evaporate water or melt snow?
The first is called enthalpy of vaporization, the second is called enthalpy of fusion.
What is a correct description of the enthalpy of reaction?
The enthalpy of a chemical reaction is the change of heat during this reaction.
Is heat of fusion physical or chemical property?
Heat of fusion is a physical property.
What is an example of a chemical property of water at 4 and deg?
For example the enthalpy of formation.
What chemical bond possess low latent heat of fusion?

Is evaporation a chemical property?
It is not a property it is the process of turning a liquid into a gas. The enthalpy change of evaporation would be a chemical property.
How do you make a sentence for enthalpy?
Enthalpy is a thermodynamic property of a thermodynamic system.
What is enthalpy of fusion vaporization?
Enthalpy of fusion/vaporization is the amount of energy added to a system to melt of boil a substance or the amount of energy removed from a system to condense or freeze a substance.
The energy required to melt one gram of a substance is known as what?
heat of fusion
Why is the enthalpy of sublimation is equal to the sum of enthalpy of fusion and enthalpy of vaporization?
Enthalpy is a state function, and to a first approximation does not depend on temperature. So the change in enthalpy to go from solid to a gas directly (sublimation) at some temperature is equal to the sum of the enthalpies associated with going from a solid to a liquid (fusion) and going from a liquid to a gas (vaporization) at other temperatures.
What is when a substance changes from a solid to a liquid?
The heat energy, or enthalpy, associated with a solid to liquid transition is the enthalpy of fusion and that associated with a solid to gas transition is the enthalpy of sublimation.
Which represent(s) a chemical property?
· General chemical properties: - Pauling electronegativity - Period - Group - Flammability - Corrosivity - Heat of combustion - Enthalpy of formation Valence (oxidation states)
What is the description of the enthalpy of reaction?
The enthalpy of a chemical reaction is the change of heat during this reaction.
What does the enthaply of reaction measure?
The enthalpy of reaction is the change of the system enthalpy after a chemical reaction.
