Topic 1: Solids, Liquids and Gases Flashcards
(19 cards)
Name the 3 states of matter.
Solids
Liquids
Gases
How are the 3 states of matter different from each other?
Solids always retain their shape.
Liquids flow and take the shape of the container. They fill the container from the bottom to a certain level and take up a fixed amount of space.
Gases also flow, but they fill up the entire space of their container. If the container opens, the gases will escape.
Although we can easily tell if we have a solid or a liquid, gases are normally _____.
invisible
Matter is made up of very small particles. What are these particles called?
Atoms and molecules.
Explain the differences in particles of solids, liquids and gases.
Solids: the particles are packed very tightly against each other and they can’t be compressed. They do not move.
Liquids: the particles are also very tightly pack and they can also not be compressed, but they move around all the time.
Gases: the particles are far apart with large empty spaces and they move around freely. They can easily be compressed.
If we want the particles in a solid, liquid or gas to move away from each other, what must we apply?
heat
If we want the particles in a solid, liquid or gas to move closer together, what must we take away?
heat
The container is a balloon.
What material is inside?
Is the material a solid, liquid or gas?
air (helium)
gas
The container is a bottle oil.
Is the material inside a solid, liquid or gas?
liquid
The container is a glass of milk.
Is the material inside a solid, liquid or gas?
liquid
The container is a kettle.
What material is inside?
Is the material a solid, liquid or gas?
water
liquid
The container is an empty jar.
What material is inside?
Is the material a solid, liquid or gas?
air (oxygen)
gas
The container is an ice tray.
What material is inside?
Is the material a solid, liquid or gas?
frozen water (ice)
solid
True or false (if false, correct the statement)
Gases automatically gather in one small area.
False
Gases automatically spread to fill an area equally.
How does water turn into steam?
When heat is applied to water, the water turns into steam.
How does water turn into ice?
When heat is removed from water until it reaches 0 degrees Celsius, the water will freeze.
How are the particles organised in a solid?
They are tightly packed and a fixed position.
How do the particles move in a gas?
The particles in a gas moves around freely because they are far apart.
How are the particles organised in a liquid?
They are tightly packed, but can still move around.
