lower specific heat
B
a lower heat of vaporization

D
a higher boiling point
Verified step by step guidance
1
Understand the concept of specific heat: Specific heat is the amount of heat required to raise the temperature of a substance by one degree Celsius. Water has a high specific heat compared to many other substances, meaning it can absorb a lot of heat without a significant change in temperature.
Consider the heat of vaporization: This is the amount of energy required to convert a liquid into a gas at its boiling point. Water has a high heat of vaporization, which means it requires more energy to vaporize compared to substances like ethanol.
Examine hydrogen bonding: Water molecules form hydrogen bonds, which are strong intermolecular forces that contribute to water's unique properties, including its high boiling point.
Relate these properties to boiling point: The high specific heat, high heat of vaporization, and strong hydrogen bonding in water contribute to its higher boiling point compared to other liquids like ethanol.
Conclude with the correct answer: Given these properties, water has a higher boiling point than other liquids such as ethanol, reflecting its capacity to absorb large amounts of heat.
