Answer:
I think it is d. 99% sure
Explanation:
When you jump into a pool, you will notice that the heat from your body flows towards the lower temperature. This happens because water is a better conductor of heat than air. As a result, when you are swimming, you will feel more relaxed than when you are in the surrounding air. The reason for this is that water is denser than air and its particles are closely packed together, which promotes faster heat transfer. This means that heat transfers more rapidly to the water, making the pool feel more comfortable than the air.
