Particle Theory and Diffusion

Hello everyone, today we are learning about particle theory and diffusion. Particle theory and diffusion is the movement of a area of high and low concentration. We first learn about matter (solid liquid and gas), matter should have a mass and a has a volume. We are going to experiment to diffuse hot water and cold water. 

Particle theory: is a particle that changes properties in different states of matter. 

• all matter is made up of particles 
• all particles is a pure substances are the same 
• There is space between all particles 
• particles are always moving 
• there are attractive forces between particles 
• temperature affects the speed at which particles move 

 

Aim: We are investigating the effect of the temperature on rate of diffusion. 

Hypothesis: I think that hot water will diffuse faster than the cold water, because heat gives more energy to spread out more than cold.           

Method:

1. put warm water and cold water into the same cylinder size and width.
2. Get some KMn04 (Potassium Permanganate)
3. Put the KMn04 (Potassium Permanganate) in the water which is the warm and the cold water and they should have the same amount.

Conclusion:

In the end the KMn04 (Potassium Permanganate) spread faster at warm water, Its because the warm water have more energy. This also because the particle is moving fast.
