Question

what are the factors on which pressure depends upon?

Answer 1

Pressure depends on the force applied and the area covered

Answer 2

Pressure is the force acting perpendicularly on unit area of the object.

Pressure depends upon the factors that follows:-

• (1)It depends on force applied.

• (2)Area over in which force acts.
• The same force can produce different pressure depending upon area in which it acts.
• When the force acts over a large area,the pressure produced is less.

Pressure = Force/Area

S.I. Unit of Pressure is N/m2 (or)Nm -2(pronounced Newton Metre to the power of minus two)

1Pascal = 1N/m2(Newton metre square) .

• Pressure also depends on the inter molecular forces of attraction present between the molecules of gases confined in a vessel.
• Greater the inter molecular forces of attractions lesser the pressure it exerts. This can be explained on the basis of vanderwals equation.
• When there is complete absence of inter molecular forces then that gas exerts more pressure on the walls of the container.Such gas is called Ideal gas.But in nature no gas is found to be ideal.
