What is the enthalpy of vaporization for chloroform?
The enthalpy of vaporization for chloroform is approximately 31.4 kJ/mol.
What is the standard enthalpy change of vaporization for CDDT?
The standard enthalpy change of vaporization for CDDT (Clotrityl chloride) is approximately 42 kJ/mol.
What is enthalpy of fusion vaporization?
The enthalpy of fusion is the heat energy absorbed or released when a substance changes from solid to liquid at its melting point. The enthalpy of vaporization is the heat energy absorbed or released when a substance changes from liquid to gas at its boiling point.
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.
Is a positive enthalpy change indicative of an endothermic reaction?
Yes, a positive enthalpy change is indicative of an endothermic reaction.

Use the data to determine the heat of vaporization of nitrogen?
To determine the heat of vaporization of nitrogen, you would need the enthalpy of vaporization data for nitrogen. This value is typically around 5.57 kJ/mol at its boiling point of -195.79°C. By knowing the enthalpy of vaporization and the conditions at which nitrogen is boiling, you can calculate the heat of vaporization.
What is enthalpy of fusion vaporization?
The enthalpy of fusion is the heat energy absorbed or released when a substance changes from solid to liquid at its melting point. The enthalpy of vaporization is the heat energy absorbed or released when a substance changes from liquid to gas at its boiling point.
The amount of energy needed to change a material from a solid to a liquid is the heat of what?
The latent heat of evaporation
Why does water evaporate quicker than liquid soap?
The enthalpy of vaporization is different.
What is the equivalent vaporization in thermodynamic?
Vaporization is the phase transition from liquid to vapor and is equivalent to the enthalpy change of vaporization in thermodynamics. This enthalpy change represents the amount of energy required to convert a substance from liquid to vapor at its boiling point. It is a key parameter in understanding the behavior of substances during phase transitions.
Why rate of evaporation decreases when common salt is added to water?
The enthalpy of vaporization is increased.
What type of energy is used when water evaporates?
The necessary heat is called enthalpy of vaporization.
Why is the enthalpy of sublimation is equal to the sum of enthalpy of fusion and enthalpy of vaporization?

Why does surgical spirit evaporate faster than water?
The ethanol enthalpy of vaporization is lower compared to water.
