Density = mass / volume
Volume = (width x depth x height) cm³
Pressure = force / area
Pressure difference = height x density x gravity
Pressure increases with depth.
Brownian motion: The particles in matter are extremely small and, in liquids and gases, they are in a continuous state of rapid random motion.
The random motion of gas and liquid particles explains why pressure acts in all directions at any point.
The speed of molecules increases with temp, so as we heat gases in a rigid container, the pressure of the gas increases.
The temp of a gas inn kelvin is proportional to the average kinetic energy of the gas molecules
