States of matter and Cooling/heating curve

Question 1

What are the three states of matter?

Answer 1

Solid
Liquid
Gas

Question 2

What is the particle arrangement like in solids?

Answer 2

Particles are close together.In a regular pattern.Held together by forces.Vibrate in a fixed position.Dont move to place to place.Particles have the least amount of energy in this state.

Question 3

What is the arrangement like for liquids?

Answer 3

Particles are close together.Not in a regular pattern.held together by weak forces.Can move around each other. Particles are still touching. Particles have more energy than the solid state but less than the gaseous state.

Question 4

What is the arrangement of particles in a gas ?

Answer 4

Particles are far apart.Not in a regular pattern. Can move quickly in any random direction. Particles have the most enrgy in this state.

Question 5

Can solid be compressed. Give a reason for your answer.

Answer 5

Solid cannot be compressed because the particles are close together in regular arrangement.Solids also have a definite shape because the particles do not move they vibrate in fixed positions.

Question 6

Can liquid be compressed?Give a reason for your answer.

Answer 6

Liquid is hard to compress because the particles can slip and slide over each other.

Question 7

Can gas be compressed?Give a reason for your answer.

Answer 7

Gas can be compressed because the particles are far apart.

Question 8

What is the process of a solid turning into a gas?

Answer 8

Subliming

Question 9

What is the process of a gas turning into a solid

Answer 9

Deposition
