in a beetroot experiment , we had to investigate the affect of heat on the relese of pigment, then we had to mesure absoption. can you tell me what are the errors involved and how to improve the experiment? plz
Difficult without knowing EXACTLY what you did. You have to look at factors (about the method, not how YOU performed) that might have led to inaccuracy. For example, an analogue colorimeter may be more inaccurate than a digital one because the needle tends to sway back and forth to some extent.
