A barometer also monitors variations in atmospheric pressure. As air becomes thinner, the density of air decreases, and so too does the pressure of air. Many different factors affect the density ...

I know which I’d prefer to try and catch! And that’s because water and air have different densities. You can think of density as how heavy something is for its size.And you can calculate it by ...

But during warmer weather, the air is less dense, and the baseball collides with few molecules. With less resistance, the ball can maintain its speed and travel further.
