The Particle Model
What is the missing word: 'M.... makes up everything around us. M... is actually made up of particles'.
Matter
What property of solids makes it different from other states at a particle level?
Particles cannot move at all.
What is the difference between the particles of a liquid and a solid?
Particles in a liquid can roll over each other.
What is an example of a gas?
Various answers accepted.
Name the change of state when a solid turns into a liquid
Melting
What happens to particles when they are cooled?
They move slower.
When you draw the particle arrangement of a solid what should you add after drawing the cirlces?
Small lines to show that the particles vibrate.
When you draw the particle arrangement of a liquid what should you add to the diagram after drawing the particles?
Arrows to show particles slowly rolling over each other.
When you draw the particle arrangement of a gas, where should the particles be in the diagram?
Diagram should have particles completely spread out and arrows showing fast movement.
Name the process by which a liquid turns into a gas.
Evaporation
Can particles change size?
No
What happens to a solid when it undergoes sublimation?
Turns into a gas.
TRUE or FALSE 'Gases can be easily compressed (squeezed) and poured'
TRUE
When a gas undergoes deposition it turns into a....
Solid
Why do solids, liquids and gases have different properties?
The particles are arranged differently.
TRUE or FALSE: 'You can compress a solid.'
FALSE. Solid have a fixed volume.
TRUE or FALSE 'Liquids have a fixed volume (amount)'
TRUE Only gases and plasma do not have a fixed volume
What happens to a gas if it is CONDENSED?
Turns into a liquid.
Name the process by which a liquid turns into a solid.
Solidification
If the particles are electrically charged, what is the state of matter?
Plasma
TRUE or FALSE 'The particles in a solid stay completely still'
FALSE They vibrate on the spot.
TRUE or FALSE 'Liquid particles will spread out and take on the shape of their container.'
True: They don't have a fixed shape
What are the 3 main gases that make up the air we breathe in?
CO2, Nitrogen and oxygen
What do we call a substance (such as cornstarch mixed with water) that acts as a solid when you apply pressure and as a liquid when there is no pressure or vice versa.
Non-Newtonian fluid.
