Unit 5: states of matter

Explaining Diffusion
Diffusion-Mahan 
-
-
Factors that determine diffusion: Temperature, size and mass of particles, state of matter. – Sivani
-
-
Amzhar: Some factors that affect diffusion are mass of solute, temperature of enviroment, density of solvent, etc
Diffusion= the spreading out and mixing of particles from areas with many particles to areas with fewer particles_Ryan Woon

Speed of diffusion depends on temperature. - Hanson Tan

Explaining gas pressure
-
Higher the temperature, the greater the gas pressure. Nitvesh
-
-
Eg; the more you blow into a balloon, the greater air particles would be inside
Anoshka 8G
Bani: The higher you are (eg mountain) the less air pressure there is the lower you (eg under the sea) the more air pressure there is.
-
Temperature can effect Air Pressure-Adam
Gas Pressure= the force exerted by gas particles when they collide with one metre square of surface_Ryan Woon.

Explaining density
-
-
Density of substance depends on: Mass of its particles, how closely packed -Mia
