So, I have an equation. * = multiplication i = initial v = final / = Division P = Pressure V = Volume T = Temperature Pi*Vi / Ti = Pf*Vf / Tf I'm not sure how to use this equation. I know that we are trying to find either Pressure Final, Volume Final, or Temperature Final. I'm not sure which one of these we are trying to find. So can someone please show me how to use this equation (providing the numbers). I have a quiz tomorrow, and I don't know how to do this. I will be forever grateful!
