A food scientist carries out an investigation to see how the length of time that cabbage is cooked in boiling water affects the vitamin C content. The table shows the results: Time cooked in boiling water (min) Vitamin C present in cabbage (%) 0 100 0.5 80 2 60 4 49 7 40 10 37 (a) What is the dependent and the independent variable in this investigation? (2) (b) How could the results be made more reliable? (1) (c) Plot the food scientist’s results on the graph paper (printed). (5) (d) Use your graph to estimate the vitamin C content of cabbage cooked in boiling water for 5 minutes. Indicate on the graph how you estimated your answer. (2) (Total for question 12 = 10 marks)
