Question

Select the two variables that are held constant when testing Boyle's law in a manometer. pressure temperature volume of gas mass of gas atmospheric pressure

Answer 1

The right options are; Temperature and mass of gas  

The two variables that are held constant when testing Boyle's law in a manometer are; temperature and mass of gas.

Boyle's law is a gas law that explains how the pressure of a gas tends to increase as the volume of the container decreases. The law states that the volume of a given mass of a gas is inversely proportional to the pressure at constant temperature. Boyle's law is expressed as PiVi = PfVf, (where Pi = initial pressure, Vi = initial volume, Pf = final pressure and Vf = final volume).

Answer 2

Answer:

a) Temperature  

b) Mass of gas

Explanation:

The Boyles’ law states that the pressure of a gas is inversely proportional to its volume (with a fixed mass). This has been proved when temperature was kept constant.

Thus, overall there were two quantities that were not changed during Boyle’s experiment  

a) Temperature  

b) Mass of gas

Hence, the formula for Boyle’s law is as follows  

$PV = k$

Where  P is pressure

V is volume and k is constant
