Question

define pressure ( write the formula with SI unit)​

Answer 1

Explanation:

Pressure—the effect of a force applied to a surface—is a derived unit, obtained from combining base units. The unit of pressure in the SI system is the pascal (Pa), defined as a force of one Newton per square meter. The conversion between atm, Pa, and torr is as follows: 1 atm = 101325 Pa = 760 torr.

Answer 2

Answer:

Pressure (symbol: p or P) is the force applied perpendicular to the surface of an object per unit area over which that force is distributed.

P = F/A (Force per unit area)

SI Unit : Pascals (Pa).
