When studying gases, irish chemist robert boyle noticed that as he changed the pressure, the volume of a gas would also change. in this experiment, what is the dependent variable? explain your answer?

In Boyel's experiment he changed the pressure and noticed the change in volume with respect to pressure keeping temperature and moles of gas constant

So here we have three kinds of quantities

a) controlled variables : Temperature and moles as they have to be kept constant

b) independent variable : pressure as we are varying it and the volume is changing with respect to pressure

c) Dependent variable: Volume , as it depends upon the change in pressure.
