What happens to pressure with an increase in depth?
Gas particles constantly collide.
The greater the depth, greater the pressure
The greater the depth the more we have the weight of the whole atmosphere above us.
An increase in the number of gas molecules, while container volume stays constant, increases pressure.
Pressure is equal is force divided by area.
