In chemicals, we are learning about the three states of matter, they are solid, gas and liquid. We also have looked at particles and the meaning behind what each state means, close meaning solid, a little far apart meaning liquid and a lot of space being gas. Solid stay close, Liquid will take volume but not shape and gas does not have a definite shape or volume and will take up the area it is in.
Diffusion: Movement of particles from high concentration to low concentration.
E.g. a smell which stinks or B.O. will spread but will lose its space taken up after a short amount of time
AIM: Observe the effect of temp on the speed of diffusion
Hypothesis: I thought it was going to not be that interesting and I thought the heated water would speed up the amount of space which the chemical would take up and the colder would be slower.
Method: We got two Petri dishes and filled either one with either cold or hot and then we got the chemical dropped in each, we observed the result
Observation and Explanation: We had put Potassium Permognate in two Petri dishes each have cold or warm water. The observation showed that the heat did speed up the amount of space the chemical took up, and the cold was at a slower pace. But in the end, they would take up all the space in the container.
The reason the hotter liquid had the chemical spread faster was that the particles in the heated liquid were moving faster and pushing out the chemical quicker.
