thebest Posted March 26, 2012 Report Share Posted March 26, 2012 If I include pressure and temperature in our controlled variables, do we have to measure the temperature/pressure of the room or can we state in the procedure to make sure to leave the solutions in consistent temp./pressure/same room?

Sandwich Posted March 26, 2012 Report Share Posted March 26, 2012 Just say they were constant. You can mention a figure for temperature if you want, but tbh it's probably not even worth it for pressure! Neither of them should realllyyyy affect osmosis all that much that I can think of!

claudika94 Posted March 30, 2012 Report Share Posted March 30, 2012 it is enough if you state that temperature and pressure stays constant the whole time. Maybe that the temperature is room temperature. And you should say how you are going to control these variables. Eg. temperature- by making sure no window or door opens during the experiment.
