Question

an experiment was set up to test the hypothesis that increasing the temperature increases the rate of diffusion. the time (in seconds) for a purple dye to diffuse through set distances in water at different temperatures was recorded. the results are shown in the table below.

water	temperature (°c)	10	20	30
4 cm		114	66	30
6 cm		210	108	55
8 cm		300	282	80
10 cm		450	222	125

a) plot each of the three data sets on a graph.

Explanation:

Step1: Identify variables

The independent variable is temperature (in °C) and the dependent variable is the time (in seconds) for the purple - dye to diffuse through set distances in water.

Step2: Prepare graph

On the x - axis, mark the temperature values (10, 20, 30). On the y - axis, mark the time values. For each set distance (2 cm, 4 cm, 6 cm, 8 cm, 10 cm), plot points corresponding to the temperature and time values. For example, for 2 cm distance, at 10°C the time is 60 seconds, at 20°C the time is 30 seconds and at 30°C the time is 12 seconds. Connect the points for each distance set to form lines.

Answer:

A graph with temperature on the x - axis and time on the y - axis, with multiple lines representing different set distances for the diffusion of the purple dye.
