Understand the concept of specific heat capacity: Specific heat capacity is the amount of heat energy required to raise the temperature of a substance by one degree Celsius. Water has a high specific heat capacity due to the hydrogen bonds between its molecules, which absorb and store heat energy.
Relate specific heat capacity to temperature stability: Because water can absorb and store large amounts of heat without a significant change in temperature, it helps regulate temperature in environments like lakes and oceans.
Analyze the options provided: Evaluate each option to determine which one directly relates to the high specific heat capacity of water. For example, 'Water acts as a universal solvent' is related to water's polarity, not its specific heat capacity.
Focus on the correct phenomenon: The option 'Lakes and oceans maintain relatively stable temperatures throughout the year' is directly tied to water's ability to absorb and release heat slowly, preventing drastic temperature changes.
Conclude the reasoning: The high specific heat capacity of water is the key factor that allows aquatic environments to maintain stable temperatures, supporting life and ecosystems throughout seasonal changes.
