Particle Theory and Diffusion

Hi, everyone! Welcome to another post. Today for science we have begun learning about particle theory and diffusion. We first learned about what matter is and how both of these topics relate to matter. After that, we learned what particle theory and diffusion is.

Particles 

Particle Theory: Particle Theory is a theory which explains the changes of properties in different states of matter.

• All matter is made up of particles.
• All particles in a pure substance 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. 

Diffusion: Diffusions is when particles move from an area that has high concentrations to an area of  low concentration 

Today we are going to do an experiment on diffusion. 

Our Aim: To investigate the effect of temperature on the rate of diffusion. 

Hypothesis: I think that hot water will diffuse faster than cold water because I think that hot water particles are more likely to spread out rapidly. 

Method:

1. Put warm water and cold water into a cylinder cup with a wide base of the same size. The containers have to be the same size.
2. Get some KMn04 ( Potassium Permanganate) 
3. Put the KMn04 in both the warm water and cold water. - They have to be the same amount. 

Conclusion: 

In the end, warm water had made the KMn04 spread out faster than the cold water. The warm water was faster than the cold water because the warm water has more energy. This is also because the particles are moving fast to spread the liquid.
