The enthalpy of vaporization of water is approximately:
Correct Answer: 2260 kJ/mol
- Step 1: Understand what enthalpy of vaporization means. It is the amount of energy needed to turn water from liquid to gas.
- Step 2: Know that for water, this energy is quite high because water molecules are strongly attracted to each other.
- Step 3: The value for the enthalpy of vaporization of water is around 2260 kJ for every mole of water.
- Step 4: Remember that 'kJ/mol' means kilojoules per mole, which is a unit of energy per amount of substance.
