Q

What is the Mathis of the delusion experiment

A

Using a forceps gently place a few potassium manganate crystals at the bottom of a beaker of water.

Observe what happens for a few minutes.

Leave your beaker. Explain what has happened to the purple particles.

17
Q

What is the result of the diffusion experiment

A

The purple colour of the potassium manganate slowly spreads throughout the water until the solution is evenly coloured.

18
Q

What is matter

A

Matter is anything that occupies space and has mass

19
Q
