Question

the enthalpy change for the reaction H2O(s)→H2O(l) is called enthalpy of
a) vaporization
b)fusion
c) combustion
d) transition ​

Answer 1

Answer:

Answer is A) Vapourisation

Answer 2

Option-(a) Vaporization

The enthalpy change for the reaction $H2O(s) --- H2O(l)$ is called enthalpy of Vaporization

Explanation:

• Enthalpy of vaporization is represented by the symbol ∆$Hvap$
• It is also known as the latent heat of vaporization or heat of evaporation
• It is the amount of energy or the enthalpy which must be added to a liquid substance in order to transform a quantity of that substance into a gas.
• It must be the quantity of heat that must be absorbed if a certain amount of liquid is vaporized.
• It may also be termed as the physical destruction of the object.
