Q5 A student carTies out an experiment in which a column of liquid glycerol flows through a narrow glass tube. The time taken for the top of the glycerol column to fall a known distance between two markers is measured with a stopwatch. The experiment is repeated at different temperatures. The student records the following results. Temperature / °C Time taken /s Average speed / ms' 26.5 4.2 0.019 35.5 2.4 0.033 0.053 42.5 1.5 50.0 1.2 0.067 61.5 0.5 0.160 (a) (i) The table shows the average speed of flow for four of the temperatures. Calculate the missing value and enter it in the table. The distance between the markers is 0.080 m.

) Use these results to explain how the viscosity of glycerol varies with temperature. (6) This experiment depends on the flow remaining laminar and not becoming turbulent. (1) Explain these two terms and complete the diagrams to illustrate each type of flow through a vertical tube. laminar turbulent (1i) Explain the effect turbulence would have on the rate of flow.
