Question

The gas exerts a total force of 5.41 N perpendicular to one of the container walls, whose dimensions are 0.127 m by 0.203 m . Calculate the pressure of the sample.

Answer 1

Answer:

482.7 atm is the pressure of the sample; it can be either 209.4 Pa

Explanation:

Pressure = Force / Area

When you apply a force in a determined area, you are making a determined pressure, provided that the force is perpendicular to that area.

Area of a wall in the container = 0.127 m  . 0.203m  = 0.025781 m²

N/ m² = pressure (Pa)

101300 Pa = 1 atm

5.41 N / 0.025781 m² = 209.84 Pa

Let's conver the value by a rule of three (by the way, Pa is a unit of pressure) .- The excerside does not state, in which unit of pressure, the answer must be.

101300 Pa ____ 1 atm

209.84 Pa ____ (209.84 / 101300) = 482.7 atm
