As per the information given, there's most probability that the air over the lake will reach its highest temperature later in the day and will stay warm longer than air over the ground.
Answer: Option A
Step-by-step explanation:
According to the concepts of the specific heats capacity of matter; it is observed that water possesses high specific heats capacity as compared to metals and other solids. Water takes much more time to absorb heat from the atmosphere and the same way takes time while releasing it into the atmosphere.
Whereas, solids and most metals have the tendency to quickly absorb and release the heat. Hence, it seems that the student may observe the rise in temperature for the air over the water lake later in the day which will stay warm longer than the air over the ground.
