how do you measure the percentage of the jelly that has changed colour?

[@btecappliedsciencehelp]

(volume that has changed colour divided by total volume) x 100%

Sir , would the exam ask you to do an experiment that you have not covered and student book 1 did not cover

[@btecappliedsciencehelp]

unlikely but possible

[@Rtqw-fg5qu]

Do you have a method for this ?

[@btecappliedsciencehelp]
