Question

Select the two variables that are held constant when testing Boyle's law in a manometer.

Answer 1

Start studying Pressure - Volume Relationships in Gases (Boyle's Law). Learn vocabulary, terms ...Select all that apply. V2 = k/P2 V2 = P1V1/P2 ... What two variables are held constant when testing Boyle's Law in a manometer? Temperature hope this helps

Answer 2

Answer: The variables which remain constant while testing Boyle's law is temperature and number of moles.

Step-by-step explanation:

Boyle's law states that pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.

Mathematically,

`P\propto (1)/(V)` (At constant temperature and number of moles)

or,

`PV=k`

With increase in pressure, the volume of the gas decreases and vice-versa.

Hence, the variables which remain constant while testing Boyle's law is temperature and number of moles.
