Answer:
The correct answer is option A, that is, ice caps.
Explanation:
The part of the planet Earth covered by water or ice is known as the hydrosphere. It comprises lakes, oceans, rivers, polar ice caps, and glaciers. The polar ice caps and glaciers are the only elements of solid found in the hydrosphere.
The other options, that is, lakes and rivers are also a part of hydrosphere but they are in liquid form. While rainforest and rocks and minerals are the parts of the lithosphere, not hydrosphere.
Answer:
Total pressure = 759 mmHg
Explanation:
Given data:
Partial pressure of oxygen = 165 mmHg
Partial pressure of nitrogen = 594 mmHg
Total pressure = ?
Solution:
According to Dalton law of partial pressure,
The total pressure inside container is equal to the sum of partial pressures of individual gases present in container.
Mathematical expression:
P(total) = P₁ + P₂ + P₃+ ............+Pₙ
Total pressure = P(O₂) + P(N₂)
Total pressure = 165 mmHg + 594 mmHg
Total pressure = 759 mmHg
Answer:
carbon dioxide hydrogen chloride carbon monoxide and nitrogen oxide
I believe it would be A, frogs and spiders, because frogs and spiders both eat grasshoppers. But I cannot see the diagram it talks about, so it's harder to tell.
Answer: increases
Explanation:
Matter exists in three different states, they are solids, liquids and gases. And each of them contains molecules with a certain amount of kinetic energy.
Hence, the addition of heat changes a substance from a liquid to a gas through a process called vaporization, whereby liquid molecules on changing to gases acquire a higher kinetic energy, and move more freely within the containing vessel.
Thus, the higher kinetic energy explains the increase in the average distance between molecules.
