The independent variable and the dependent variable

Independent variable is temperature and dependent variable is volume

Explanation:

In his experiment a sample of a gas has been taken to find the effect of temperature on the volume of a gas at constant pressure.

To conduct this experiment we will change the temperature of the gas and see the change in its volume.

I other words, volume of the gas will depend on its temperature.

So the independent variable is temperature and dependent variable is volume.

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.
