Question

Merry is a lab technician with a manufacturer of medical supplies. She is using Boyle's Gas Law to test the pressure inside a syringe her company will distribute for drawing blood. When the plunger of a syringe is at a volume of 2 cubic centimeters, the pressure inside the syringe is 0.4 lbs/psi. Which equation could Merry use to find the pressure inside the syringe when the volume is 6 cubic centimeters ?

Answer 1

The pressure inside the syringe is 1.2 lbs/psi when the volume is 6 cubic centimeters.

Explanation:

We are given the following in the question:

When the plunger of a syringe is at a volume of 2 cubic centimeters, the pressure inside the syringe is 0.4 lbs/psi.

Boyle's Gas Law

• It states that the pressure of a gas is inversely proportional to volume of gas at a given temperature.

Thus, we can write:

`(p_1)/(v_1) = (p_2)/(v_2)`

We have to find the pressure inside the syringe when the volume is 6 cubic centimeters.

Putting values, we get,

`(0.4)/(2) = (p_2)/(6)\\\\p_2 = (6* 0.4)/(2) = 1.2`

Thus, the pressure inside the syringe is 1.2 lbs/psi when the volume is 6 cubic centimeters.
