the force of the atmosphere on the earth's surface Answer by FutureLPGAgolfer
Force per unit area.
The amount of force acting on a unit mass. The equation is pressure is force divide by area.
Pressure is the amount of Force per unit area.

∙ 12y agogas pressure is the average pressure of a gas................................................. not a very detailed answer (although true.)............
Gas pressure is the pressure of gas when contained. Pressure is when something is compressed and particles move around bouncing off the sides of the container (trying to escape and expand). The more particles there are in a certain space, the higher the pressure. For example, the air pressure in a car tyre is how many air particles are compressed into the tyre. Air pressure can be measured using a barometer and gas pressure can be measured with a manometer. All types of pressure (that I am aware of) have the same characteristics. ................. Please research further as I am not 100% sure of my answer.

∙ 11y agofirst of all, pressure is formed when force/m2 + some amount of pascals but one pascal is really small, so how you do it with gas is put some compound or element on the Periodic Table (helium) inside some room and if you put in more helium the amount of pascals rises. But the thing with helium is that it has a aster velocity level than oxygen and the Atomic Mass is only 4.00 so for certain gas you may need more or less.

What causes the pressure that a gas exerts on the wall of its container?
Kinetic theory explains the pressure that a gas exerts on the walls of its container. This describes elastic collisions between the atoms or molecules in the gas with the container's walls, which collectively exert a measureable pressure.
The volume of a gas is directly proportional to the number of moles of that gas if?
the pressure and temperature are held constant. ideal gas law: Pressure * Volume = moles of gas * temperature * gas constant
Equation of boyle's law?
Boyles Law refers to the way gas and pressure interact. It says that the pressure of a gas times the volume of the gas will equal a constant. The constant is supposed to represent an "ideal gas."
When the pressure of a gas increases at constant temperature its volume?
Temperature increases as pressure increases.
What will happen to gas pressure when the volume is decreased?
When the temperature of a gas is increased at a constant pressure, its volume increases. When the temperature of a gas is devreased at constnt pressure, its volume decreases.
What term best describes a gas under greater than atmospheric pressure?
compressed gas
How many psi in 1 cubic foot of gas?
There can be aby number of psi in a cubic foot because psi is a measurement of pressure and the gas can be any pressure you care to make it.
A piston in an engine compresses the gas into a small volume What is the pressure?
The pressure is higher than it was at first. A measurement cannot be given from these details.
What is the name of the machine measuring pressure of gas?
Many techniques have been developed for the measurement of pressure and vacuum. Instruments used to measure pressure are called pressure gauges or vacuum gauges.
What relationship does boyle's law describe?
The relationship between pressure and volume (apex)
What describes how pressure affects volume?
Ideal gas law. At a fixed temperature, the pressure and volume are inversely related. PV=mRT
What gas law describes when adding gas to a balloon will cause the volume to decrease?
The volume decrease only when the external pressure increase.
Which gas law describes the volume of a balloon increasing on a mountaintop?
Boyle's Law which relates volume to pressure.
What is the relation between pressure and temperature?
In general, when you have a system at a constant volume, pressure will increaseas you increase its temperature. In the particular case of an ideal gas where the relation between pressure P, absolute temperature T and volume V is given byPV =nRT(where n is moles and R the Universal Gas Constant), pressure is directly proportional to the absolute temperatureof the gas.Temperature and pressure are very much inter-related via the Ideal Gas LawPV=nRTThe major different would be that Temperature is a measurement of kinetic energy, while pressure is measurement of force per unit area.
What is millivoltge a measurement of?
Voltage- the measurement of electrical 'pressure'.
Which term describes changing a measurement to an equivalent measurement of different unit?
Conversion.
Ideal gas law behavior of real gases under?
the ideal gas law describes that the behavior of real gases under all conditions of temperature and pressure.
