Identify at least two advantages of breathing air instead of water.

Video transcript

Hello everyone and welcome to today's video. So today we need to understand why air is a better respiratory medium than water. So what reason makes air a better respiratory mediums? We're giving these answer choices that could explain this. Let's begin by answer choice. A The oxygen content of air is much higher than the oxygen contour of an equal volume of water. This is actually going to be a correct statement because air contains 21% oxygen. Wall water Contains very little dissolved oxygen, which is usually less than 1%. So there is obviously More oxygen in air, which makes it a better respiratory medium. So let's move on to answer choice. B the oxygen diffuses about 8000 times more quickly in the air than in the water. But let's also talk about sea air is less than than water. These to answer choice have to do with air being a gas and water being liquid. Since air is a gas, it will diffuse much faster than water being a liquid. But also because air is a gas, it is going to be less dense or less heavy than water being a liquid. So these two answer choices are actually going to be correct as well and we will not cancel it out. Since we were not able to cancel out any of our answer choices. The correct answer choice is going to be all of the above. That is the final answer to a question and I really hope this video helped you
