PSI
This is the combined gas law: pV=nRT.
What in the community relates to air pressure?
The equation that relates pressure, force, and area is: Pressure = Force / Area. This equation states that pressure is equal to the force applied per unit area.
Pressure is a scalar quantity. It is defined as the force per unit area and only has magnitude, not direction.
Pressure is the physical quantity measured in bar.
SCALAR
Pressure =Force/Area
Pressure is no vector. Pressure is a scalar. Pressure-gradient is a vector.why pressure is a scalar
Yes.
Electrical pressure
Yup! We know that the scalar quantity is a quantity which is having magnitude but not having "DIRECTION" pressure is a scalar quantity for the reason that it's not having any direction Means it is directionless...... Have you ever heard saying anyone that the pressure applied was 730 torrs in west , east or north south direction?????????> No, it is IMPOSSIBLe.....
The quantity of gas in a given volume can be determined by two important gas equations. PV=nrT relates pressure and volume to the Ideal Gas Law constant, the amount of moles of gas and the system temperature. Once the system of the pressure (in atms), temperature (degrees Kelvin), gas constant (.0821 L*atm*K^-1*mol*-1), and volume (L) are known gas quantity in moles can be calculated.
