Question

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?

Answer 1

The dependent variable in Robert Boyle's gas experiments was the volume of the gas, which varied inversely with changes in pressure, as described by Boyle's Law.

Step-by-step explanation:

When Irish chemist Robert Boyle performed his experiments on gases, he observed a phenomenon that is now known as Boyle's Law. The dependent variable in Boyle's experiments was the volume of the gas. This is because as Boyle changed the pressure, he noticed that the volume of the gas would change in response; hence, the volume depended on the pressure exerted on the gas. According to Boyle's Law, at constant temperature, the pressure and volume of a given amount of gas are inversely proportional to each other.

Answer 2

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.
