Particle theory Flashcards
Name the properties of a solid
close together
Aranged in a regualar way
Name the properties of a liquid
close together
arranged in a random way
Name the properties of gas
far apart
Aranged in a random way
Tell me for each material, how do they move
solid-vibrate on the spot
liquid-Move around each other
gas-move freely
What are the four steps to making a theory?
Hypothesis- Explain why things happen and used to make a prediction
Make a prediction-What do you expect to observe
Test your prediction-use an experiment to make an observation
Repeat the experiment serveral times to test it-if it holds up it becomes a theory
Explain Brownian motion
the irregular random movement of microscopic particles in a fluid. It bumps into each other and creates a larger partical. The particals move randomly
What is diffusion
Diffusion is the movement of particles that allows them to spread out and mix with other particles
