nordsb [41]3 years ago
6 0

Answer:

With the changes in atmospheric pressure, the gas laws also change accordingly, that is, the Charle's law, the Boyle's law, the Ideal Gas Law, and the Gay-Lussac's law changes with the change in atmospheric pressure. Therefore, the planets, which exhibits the constant value of atmospheric pressure will be more reliable, and those possessing different atmosphere or no atmosphere will be the least reliable.

The phrase "Most ecosystems are solar powered" refers to the fact that most organisms seek sunlight. solar energy is converted t
Savatey [412]

Answer:

The solar energy is converted to chemical energy by the process of photosynthesis - This is the true statement of the given question.

Explanation:

An ecosystem usually refers to the biological community comprising all the types of living species that are continuously interacting with the surrounding environment. Most of these ecosystems are solar-powered, and by this phrase, it means that there occurs the transformation of energy from solar to chemical energy which is taking place due to the process of photosynthesis. Both the terrestrial and the aquatic, are able to carry out this process in the presence of sunlight, water, and CO₂, and in return, it liberates food and oxygen into the ecosystem.

Thus, this statement satisfies the given phrase.

All other options are false as it does not justify the phrase.

Explain how you would separate a mixture of sand and water.
Nata [24]

Answer: When sand is added to water it either hangs in the water or forms a layer at the bottom of the container. Sand therefore does not dissolve in water and is insoluble. It is easy to separate sand and water by filtering the mixture. Salt can be separated from a solution through evaporation.

Which gas has the highest diffusing rate between nitrogen , oxygen , hydrogen and chlorine
Vilka [71]

Answer:

hydrogen

Explanation:

The gas with the least molecular weight effuses the fastest (Graham's Law). Hence, H gas has a higher rate of diffusion compared to N, O, and Cl.

So, Cl is the slowest when it comes to the rate of diffusion, because it has the highest molecular weight.
