Answer:
the submarine floats after replacing the water with the compressed air
In the ocean, solar energy is rapidly absorbed or reflected in the upper surface, leaving little energy to penetrate deeper, and so deeper water is not heated (this also explains the lack of light deep in the ocean). Additionally, warm water is less dense than cold water, and so cold water will sink while warm water floats above it.
Thus, temperature of the ocean also varies from top to bottom, giving a vertical structure to most of the ocean. This vertical structure has a large impact on how life is distributed in the ocean.

Answer:
Yes. Burning usually observes this kind of law.
Explanation:
- The law of conversion of mass states that mass can never be formed nor can it be eradicated.
- This means that in case of burning, the amount of matter before and after will remain to be the same.
- It doesn't change at all.
- In conclusion, there's no form of change that can be able to affect matter.
