Question

(15) State the formula for pressure. Hence, determine the unit of pressure,
Ans.​

Answer 1

Answer:

The formula to measure pressure is Pressure equals force in pounds over the area in square inch. The written abbreviated formula is P= F/A. By looking at the formula one can see that top obtain the pressure on an object, one must divide the the force by the area of an object.

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.

hope it helps u....

plss mark me as the brainliest!!

Answer 2

Explanation:

Pressure is defined as the normal force per unit area of a surface. If F is the force acting normal to the surface area A,then the pressure P is given by : P = F/A, Newtons/square meter or P = F/A Pascals
