Question

you can painlessly wade into a pool, but doing a belly flop off of the high diving board hurts because of multiple choice waters higher density compared to the air. a neutral ph. adhesion of your molecules with the water molecules. waters high boiling point. cohesion of the water molecules.

Explanation:

Water has a higher density than air. When wading into a pool, the body enters the water slowly and the force is distributed gradually. But in a belly - flop from a high diving board, the body hits the water surface with high speed. The high - density water resists the body's motion more forcefully than air would, causing pain. The other options like neutral pH, adhesion, high boiling point, and cohesion are not related to the pain from a belly - flop.

Answer:

water's higher density compared to the air.
