Question

Suggest an activity to show that the rate of diffusion of liquids increases with increase in temp.

Answer 1

Answer:

At higher temperatures, the rate at which fluid particles will diffuse is faster than at lower temperatures.

Activity:

EXPERIMENTAL PROCEDURE

1. Fill one cup ¾ full with hot tap water.

2. Fill another cup ¾ full with cold tap water.

3. Then, at the same time, put two drops of red and

two drops of blue food coloring gently into the

water in each cup. You will need two people to

make sure the drops go into each cup at the same

time.

4. Observe what happens in each cup over the next

5–10 minutes.

Diffusion is complete when the

solutions are uniformly purple.

Observation:

In this experiment, the food coloring will diffuse faster in the hot water than in the cold water.
