A student is investigating temperature changes at a nature preserve on a hot, clear day. Each hour, the student takes two temper
atures: one over the ground, and one over the water of a lake. During this investigation, which observation is the student MOST LIKELY to make? A. Air over the lake will reach its highest temperature later in the day and will stay warm longer than air over the ground.
B. Air over the lake will reach its highest temperature earlier in the day and will stay warm longer than air over the ground.
C. Air over the lake will reach its highest temperature later in the day and will cool off more quickly than air over the ground.
D. Air over the lake will reach its highest temperature earlier in the day and will cool off more quickly than air over the ground.
A. Air over the lake will reach its highest temperature later in the day and will stay warm longer than air over the ground.
Explanation:
The most likely observation the student will record is 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.
This phenomenon between the differences in land and water temperature causes land sea breeze to occur.
Water has a very high specific heat capacity.
This implies it takes more heat to cause a monumental increase in its temperature.
It is expected that the student will observe that the air over the lake body will reach its highest temperature later in the day. It would have gotten heated with time.
A body such as water in a lake with a high specific heat capacity stays warm for a longer period of time compared to other substances.
Metals do not have high specific heat capacity and would not stay warm for long. They quickly lose heat.
Through the process of respiration , in lung the carbon dioxide from the blood is exchanged with oxygen.
The smallest dunctional unit if the lung is the alveoli
At this level the gases are exchange through the capillaries present close to the alveoli.
The concentration gradient ,meaning the greater amount of oxygen present in the lungs and greater amount of carbon dioxide in the blood creates a gradient that allow the movment of oxygen into the blood and carbon dioxide in the alveoli through the membrane .
Partial pressure created allows the easy movement .The carbon dioxide get into the trachea and expelled through nose and mouth.
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
