Solid
What is a solid?
A material that has tightly condensed particles
What is a liquid?
A substance that has loosely packed particles in groups
What is a gas?
A substance who's particles are free moving
What is plasma?
A super heated gas
What causes states of matter to change?
More energy
What is the process of a solid turning into a liquid called?
Melting
What is the process of a liquid turning into a gas called?
Evaporation
What is it called when a gas turns into a liquid?
Condensation
What moves faster? Gas or plasma?
Plasma
Why do we draw/display particles and spheres/circles?
It makes things easier. Particles are all different so using spheres allows us to work with them without memorizing endless different particle appearances.
When a solid starts to turn into a liquid, what is that point called?
When a liquid turns into a gas, what point has it reached?
Boiling Point
What is a property of gas?
Fills its container. most are invisible, flows, particles move in one direction and bounce of objects, etc.
What is a common example of plasma?
Lightning
What are 3 of the 5 properties of matter?
Particles are always moving
particles are attracted to each other
All matter is made up of particles
Each substances has its own kind of particle
Particles at a higher temperature move faster
What are the properties of a solid?
Tightly packed particles
Low energy
Can't pass through them
Fixed shape and volume
What is it called when a liquid turns into a solid?
Freezing
Name an example of a gas turning into a liquid.
Rain
Plasma makes up what percentage of the universe?
99.9%
What is matter?
Anything that has mass or takes up volume
Why is sand/sugar a solid and not a liquid?
These particles are not as strong and dont hold together in a large group. It mimics the flowing property of liquid but does not take the shape of its container perfectly and individual grains can be picked up.
What are the properties of a liquid?
Loosely packed particles
More energy than a solid
Takes the shape of its container
Can move through with effort
All matter is made up of particles. So even if a room is empty it still has air or walls and therefore has particles
What is removed from a gas to make plasma and how?
A gas is super heated which strips it of its electrons and protons, making it super charged
Name something on this planet that is not made of matter.
Nothing
