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.
Pressure in the atmosphere is a result of the weight of the air above a certain point, while pressure in a closed container is caused by the collisions of molecules with the walls of the container. Both pressures are measured in units of force per unit area (such as Pascals or atmospheres), but they are the result of different mechanisms.

What is the difference between atmosphere pressure and water pressure?
Atmospheric pressure is the pressure exerted by the weight of the atmosphere above a given point, while water pressure is the force exerted by water on an object or surface due to the depth of the water. Atmospheric pressure decreases with altitude, while water pressure increases with depth.
What is the relation between pressure and surface area?
Pressure is inversely proportional to surface area. This means that as surface area decreases, pressure increases and vice versa, given a constant force. This relationship is described by the equation: Pressure = Force / Area.
What is one standard atmosphere of pressure in kilopacals?
One standard atmosphere of pressure is equivalent to 101.325 kilopascals.
What is a barologist?
A barologist is a term that refers to a scientist who studies pressure in the atmosphere, particularly in relation to weather patterns. They analyze barometric pressure and its effects on the environment to better understand atmospheric conditions and predict weather changes.
What is relation between pressure and speed of fluid?
According to Bernoulli's principle, there is an inverse relationship between the pressure and the speed of a fluid in motion. As the speed of a fluid increases, the pressure decreases, and vice versa. This principle is often used to explain the behavior of fluids in various applications such as in pipes, jets, and aircraft wings.
Has any relation between osmosis pressure and water activity?
There is definitely a strong relation between osmosis pressure and water activity. Osmosis is the movement of water from high pressure to low pressure.
What is the relation between pressure and friction?
Friction is directly proportional to pressure.
What is the relation between pressure and force?
Pressure is defined as force per area
What relation between pressure and height?
Pressure decreases as height increases and vice-versa.
What is the relation between force and preesure?
Pressure = force / area
How is volcanoes related to physcis?
Pressure. Do a Google search on the relation between volcanoes and pressure, or even your question.
Which fundamental force contributes to oressure in both water and the atmosphere?
The electromagnetic force contributes to pressure in both water and the atmosphere. In water, this force between water molecules results in pressure, while in the atmosphere, the force between air molecules creates atmospheric pressure.
How does the amount of gravity on a planet affect the thickness of the atmosphere?
It is not a linear relation but, the larger the planet, the greater the gravity, the more it is able to attract and keep.
What is the difference of pressure between the atmosphere and pressure in the lungs?
Not much. You create slight changes in pressure when you breathe, but it's almost insignificant.
What is relationship between atmosphere and pascal unit of pressure?
The atmosphere is a unit that represents atmospheric pressure at sea level, which is equivalent to about 101,325 pascals. The pascal is the SI unit for pressure, where 1 atmosphere is equal to 101,325 pascals.
Breathing occurs because of air pressure differences between the lungs and the?
Atmosphere
How can pressure differences in Earth's atmosphere contribute to winds?
Pressure differences in Earth's atmosphere create areas of high and low pressure. Air flows from high pressure to low pressure, creating wind. The greater the pressure difference between two areas, the stronger the resulting winds will be.
