An empty plastic bottle is sealed in a cool room and then moved to a very hot room. What can best be stated about the air pressu
mel-nik [20]
<span>A fast moving stream of air has a lower air pressure than a slower air stream.  As the stream of air moved over the top of the paper, the air pressure over the paper dropped. The air pressure underneath the paper stayed the same.  The greater air pressure underneath lifted the paper strip and it rose. The idea that a moving air stream has lower air pressure than air that is not moving is called “Bernoulli’s Principle”.

</span>The force of the moving air underneath the balloon was enough to hold it up.  The weight added by the paper clip prevents the balloon from going too high.  But that is only part of the story.  The balloon stays inside the moving stream of air because the pressure inside is the air stream is lower than the still air around it. As the balloon moves toward the still air outside of the air stream, the higher pressure of the still air forces the balloon back into the lower pressure of the air stream.  Bernoulli’s Principle at work again!

Summarize the relationship between volume, temperature and pressure (use words like “inversely
Alinara [238K]

Answer:

P and V: inversely proportional

P and T: directly proportional

V and T: inversely proportional

Explanation:

For pressure and volume, as the volume goes up, meaning the container gets bigger, the pressure would go down. There would be more room in the container, so there would be less collisions between the molecules themselves and between the molecules and the container. This makes them inversely proportional.

For pressure and temperature, as the pressure goes up, there are more collisions, so the particles move faster. Temperature is the speed of the particles, so, since both pressure and temperature would go up at the same time, they are directly proportional.

For volume and temperature, this is similar to the PV relationship. As volume increases, there are less collisions between the particles. This means that the particles are going to move slower. Therefore, as volume goes up, temperature goes down, so they are inversely proportional.

Sorry this is super long, but I hope it fully explains the question for you! ☺

Why is the increasing amount of carbon dioxide being taken up by the oceans a cause for concern?
Anna007 [38]

Answer;

-More carbon dioxide causes an increase in carbonic acid (H2CO3) which leads to a decrease in the concentration of carbonate ion (CO32-).

Explanation;

-Carbon dioxide is added to the atmosphere whenever people burn fossil fuels. Oceans play an important role in keeping the Earth's carbon cycle in balance.

-As the amount of carbon dioxide in the atmosphere increases, the oceans absorb a lot of it. In the ocean, carbon dioxide reacts with seawater to form carbonic acid which causes the acidity of seawater to increase.

-As long as we keep putting extra carbon dioxide in the atmosphere, the acidity of the ocean will continue to increase. The effect is that; Increasing acidity makes it harder for corals to build skeletons and for shellfish to build the shells they need for protection. Corals are particularly important because they provide homes for many other sea creatures.
