DEFEND THE PARTICLE THEORY

Dr Spacey and Dr Kendra!
Can you help us out defending the particle theory of matter to the GROB?

Anyone else remember any experiments showing evidence for the particle theory of matter?

Yesterday the lunch room was like a conference centre and everyone was trying to defend the particle theory but today some people were very interested in the continuum theory from GROB.

Today it has become more like a debate - Dermot is the referee, (more power to him! - as we say in Ireland).

As you know all serious scientists accept the particle theory for many good reasons.

Help us out by posting comments that defend the particle theory........

The particle theory tells us that there are spaces between all particles of matter.
This is the experiment that provides evidence for that.

Alcohol and Water Experiment.
1. Get pipette and test tube (10ml). with the pipette get 5ml of water with food colouring in it and put it in the test tube.
2. Turn the switch on the burette and slowly pour the rubbing alcohol(90% alcohol) into the test tube above the coloured water you should see the line separating the two different liquids. Fill the test tube completely
3. Put your thumb on the end of the test tube and shake it vigorously. you should feel a suction on your thumb.
4. Without taking your thumb off the top of the tube notice that a bubble appears inside the tube that was not there before. They is the space that the alcohol did take up but now doesn't because the alcohol particles fit between the water particles ans the whole lot together takes up less space than adding the alcohol space and the water space together.
This provides evidence that there is space between all particles because the two liquids mixed and the rubbing alcohol filled in the gaps between the water particles.
