effect on the permeability
... I would be testing on the effects of how the decrease of temperature would effect the release of red pigment, instead of the increase of temperature, so I had to settle for 24 degrees Celsius. ... This will mean extra diffusion may have occured whilst being left with kinetic energy from the temperature increase, having further effect than the other test fluids both for the same temperature range and for the whole of the tests of the investigation.
