In This Lesson:
We will do an experiment that shows how the temperature affects the kinetic energy and the motion of molecules of matter.

Tools:


Steps:
1. Add two drops of the red dye to the center of each beaker at the same time.

2. Start the two stopwatches at the time that the drops of red dye added to each beaker.

3. Record the time that the drops of the red dye take to completely spread out all over the water in each beaker.


Observation
The red dye spreads out faster in the hot water beaker than the cold-water beaker.

Conclusions:
In hot water beaker,
- Hot water has more thermal energy, so molecules of hot water have more kinetic energy and move faster.
- So, this causes the red dye takes less time to spread out in the hot water.

In cold water beaker,
- Cold water has less thermal energy, so molecules of cold water have less kinetic energy and move slower.
- So, this causes the red dye takes more time to spread out in the cold water.



بالتوفيق
