Particle theory

Question 1

Name the properties of a solid

Answer 1

close together

Aranged in a regualar way

Question 2

Name the properties of a liquid

Answer 2

close together

arranged in a random way

Question 3

Name the properties of gas

Answer 3

far apart

Aranged in a random way

Question 4

Tell me for each material, how do they move

Answer 4

solid-vibrate on the spot
liquid-Move around each other
gas-move freely

Question 5

What are the four steps to making a theory?

Answer 5

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

Question 6

Explain Brownian motion

Answer 6

the irregular random movement of microscopic particles in a fluid. It bumps into each other and creates a larger partical. The particals move randomly

Question 7

What is diffusion

Answer 7

Diffusion is the movement of particles that allows them to spread out and mix with other particles
