CC1 Flashcards
What is the kinetic particle theory ?
It explains the properties of different states of matter
What are the three states of matter ?
Solid,liquid,has
How are particles in a solid arranged ?
Very tightly packed together in ordered rows
How are particles in a liquid arranged ?
Tightly packed together but with small gaps to allow small amount of movement, no order to the particles
How are gases arranged ?
Very spread out with no structure or order to the particles
How do particles move in a solid ?
They can vibrate and as they are tightly packed together the vibrations are carried throughout the whole thing
How do particles in a liquid move ?
They can move around each other in the small gaps however they are all constantly touching each other
How do particles in a gas move ?
They move randomly and quickly in all directions around each other bouncing of objects
What properties do solids have an why ?
Solids have a fixed shape and therefore can’t flow, this is because they are very tightly bonded
Solids cannot be compressed or squashed as they are so tightly packed that there is no space to move into
What properties do liquids have and why ?
Liquids can flow and take the shape of their container, this happens as there particles can move around each other
Liquids can not be compressed or squashed as they are very tightly packed together
What properties do gases have and why ?
Gases flow and completely fill there container because there particles can move in all directions
Gases can be compressed as there particles are far apart and have lots of space to move into
What is the process when solid goes to liquid ?
Melting
What is the process when liquid changes to gases ?
Evaporation
What is the process when gas changes to liquid ?
Condensation
What is the process when liquid changes to solid ?
Freezing
