Boyle's law states that the volume of a gas is inversely proportional to it's pressure if the

if the temperature remains unchanged

Explanation:

Boyles Law is an experimental gas law that describes how the pressure of a gas tends to increase as the volume of the container decreases

Mathematically, Boyle's law can be stated as:

P ∝ 1 V {\displaystyle P\propto {\frac {1}{V}}} P\propto {\frac {1}{V}}  Pressure is inversely proportional to the volume

that would be b i just took the test : )

a and c

c is 100% but i am confused in a
