C
High density as a solid
D
Low surface tension
Guida verificata passo dopo passo1
Understand the concept of specific heat: Specific heat is the amount of heat energy required to raise the temperature of a substance by 1 degree Celsius. Water has a high specific heat due to the hydrogen bonds between its molecules.
Recognize the role of hydrogen bonds: Hydrogen bonds in water require significant energy to break. This means water can absorb a lot of heat without a large increase in temperature, and release heat slowly as it cools.
Relate high specific heat to climate moderation: Water's high specific heat allows it to absorb heat from the sun during the day and release it slowly at night, helping to stabilize temperatures in the environment.
Eliminate incorrect options: Nonpolar covalent bonds do not apply to water, as water is a polar molecule. High density as a solid is incorrect because water is less dense as a solid (ice). Low surface tension is also incorrect, as water has high surface tension due to hydrogen bonding.
Conclude that high specific heat is the correct property: This property of water is primarily responsible for its ability to moderate Earth's climate by absorbing and releasing heat with minimal temperature changes.
