Atmospheric pressure is the surrounding pressure around us. We live in the atmosphere and treat the atmospheric pressure as the base pressure. A pressure gauge would read 0 at atmospheric pressure. When we define the pressure in scientific way of absolute pressure, we need to add up an atmospheric pressure to the measured pressure.
These have a inverse relation. You will need to know the discharge and the incoming pressure in order to find out the mass flow rate.
The relation between density and pressure can be understood well with the help of the following derivation. Force = Mass x Acceleration →1 Pressure = Force / Area » Force = Pressure x Area →2 Equating 1 & 2 Pressure x Area = Mass x Acceleration Pressure = Mass x Acceleration / Area →3 Density = Mass / Volume » Mass = Density x Volume Eqn. 3 Becomes Pressure = Density x Volume x Acceleration / Area →4 i.e., Pressure is directly proportional to density.The relationship between density and temperature is the higher the temperature, the less the density.
A submarine deep in the ocean is under great pressure, and a space capsule outside the atmosphere is under zero pressure. Both of them are capable of high acceleration, zero acceleration, and anything in between. The pressure is irrelevant.

There is definitely a strong relation between osmosis pressure and water activity. Osmosis is the movement of water from high pressure to low pressure.
Friction is directly proportional to pressure.
Gravity holds the atmosphere in place. In fact, it perfectly balances the upward pressure gradient force (air pressure decreases as you go up in the atmosphere, causing a gradient that would otherwise generate a VERY strong wind upward). This is called hydrostatic equilibrium.
Pressure is defined as force per area
Pressure decreases as height increases and vice-versa.
Pressure = force / area
There is none.
Pressure. Do a Google search on the relation between volcanoes and pressure, or even your question.
It is not a linear relation but, the larger the planet, the greater the gravity, the more it is able to attract and keep.
These have a inverse relation. You will need to know the discharge and the incoming pressure in order to find out the mass flow rate.
Not much. You create slight changes in pressure when you breathe, but it's almost insignificant.
