Explanation:
The correct answer is option 'B', which means that statement 2 only is correct.
Water requires more energy to change its temperature because of its high heat capacity. This means that it takes a larger amount of heat energy to raise or lower the temperature of water compared to air.
Let's break down the given statements to understand why option 'B' is correct:
Statement 1: The water temperature changes more rapidly than the temperature of the air.
This statement is incorrect. In fact, the temperature of water changes more slowly than the temperature of air. This is because water has a higher specific heat capacity than air.
Specific heat capacity is the amount of heat energy required to raise the temperature of one unit of mass of a substance by one degree Celsius. Water has a higher specific heat capacity than air, which means that it takes more energy to raise the temperature of water than it does to raise the temperature of air.
Statement 2: Larger amounts of heat energy must be added to or taken away from water to raise or lower its temperature.
This statement is correct. As mentioned earlier, water has a higher specific heat capacity than air, which means that it takes a larger amount of heat energy to raise or lower the temperature of water compared to air.
In practical terms, this means that water can absorb a lot of heat energy from the environment without experiencing a large change in temperature. This is why large bodies of water, such as oceans and lakes, take a long time to warm up or cool down.
Conclusion:
In conclusion, statement 2 is correct because water has a higher specific heat capacity than air, which means that it takes a larger amount of heat energy to raise or lower the temperature of water compared to air. Statement 1 is incorrect because the temperature of water changes more slowly than the temperature of air due to water's higher specific heat capacity.

Specific heat capacities provide a means of mathematically relating the amount of thermal energy gained (or lost) by a sample of any substance to the sample's mass and its resulting temperature change.
Water has a high specific heat capacity.
A substance with a high specific heat capacity is a substance that requires a relatively large quantity of heat to cause a small temperature change. Because of this, water does not change its temperature as rapidly as other substances that are heated in the same manner.
Water temp does not change more rapidly than the temp of air as more amount of heat energy is needed to change the temp of water than air.
