Final answer:
High heat of vaporization refers to the amount of energy required to transform liquid water into water vapor. This is due to the network of hydrogen bonding between water molecules. Water has a heat of vaporization value of 40.65 kJ/mol.
Step-by-step explanation:
High Heat of Vaporization of Water:
Water in its liquid form has an unusually high boiling point temperature, a value close to 100°C. As a result of the network of hydrogen bonding present between water molecules, a high input of energy is required to transform one gram of liquid water into water vapor, an energy requirement called the heat of vaporization. Water has a heat of vaporization value of 40.65 kJ/mol. A considerable amount of heat energy (586 calories) is required to accomplish this change in water. This process occurs on the surface of water. As liquid water heats up, hydrogen bonding makes it difficult to separate the water molecules from each other, which is required for it to enter its gaseous phase (steam). As a result, water acts as a heat sink, or heat reservoir, and requires much
