Today, 11:06 AM ![]() ![]() | obviously year 11.... the main source of error is the open nature of the experimental set up of your colorimeter (this means that there is sufficient heat loss to the surroundings)... in industry, they are closed and work automatically, so that another error would be human error in parallax in reading from the thermometer etc
