pressure = height of column × density of the liquid × gravitational field strength The density of water is 1,000 kg/m 3. Calculate the pressure exerted by the water on the bottom of a 2.0 m deep ...

so as water vapor increases, the density of air decreases. Temperature also changes the density of air. As air gets warmer it expands and becomes less dense, causing atmospheric pressure to fall.

Density in particular is an important ... Anders Celsius defined a temperature scale in which the freezing point of water (at sea-level pressure) was taken as a lower reference point with a ...
