Make up your mind Google AI. Is sound faster in air that is less dense or more dense?
Honestly, there is so much wrong in the AI answers that it's hard to know where to start, but the direct contradiction of itself seems like a good start.
In water at least both higher temperature and higher pressure will result in higher sound velocity. Weird that it is different for air. I would have assumed that they behave the same.
I guess that the fact that water is incompressible must have something to do with it.
