Solids Liquids And Gasses Flashcards
What is the property of matter
What is it made from
Does material change - give examples
Yes eg ice melts, water freezes, water can be turned to steam
You can blow a balloon with air or gas and it changes shapes
What is the difference between solids and liquids
Solids can be held or are are in a fixed shape and can only change shape through force Eg cutting wood but liquids cannot be held. Liquids take the shape of the container
Do gassess have a shape
Gasses do not have a shape, they take up any free space. This is why the smell of a gas can move around a room.
What is the opposite of condensation
Evaporation
Some changes or transformation of matter are reversible and other changes are irreversible what does this mean
Sometimes changes can be reversible with things like melting of chocolate it’s a solid that then changes into a liquid but it can be made into a solid again by cooling it down and letting it harden
Changes are not reversible once toast has been toasted it has been heated it cannot be untoasted
Describe what a solid is
A solid is a state of matter in which the particles are tightly packed together in a regular pattern giving them a fixed shape and volume.
The particles in a solid are together by strong intermolecular forces which make it difficult for them to move around ..
Solids can be either crystalline (well-defined repeating pattern) or amorphous (not having a well-defined pattern)
Diamond, table salts and courts example of crystalline solids
Gas plastics and rebel examples of amorphous solids
What is a crystalline solid
It is a solid with a well-defined, repeating pattern e.g. diamonds, table salt
Describe the state of matter of a liquid
Liquids have particles that are less tightly packed than solids. This means they can move around and flat past one another. This means that liquids have a fixed volume but not a fixed shape so they take on the shape of their container.
Like solid liquids have strong intermolecular forces holding their particles together but these forces are weaker than those in solids
Describe the make up of gases
Gases are a state of matter in which particles are very far apart and move around rapidly. This means that gases do not have a fixed shape or volume and will fill any container they are placed in. The intermolecular forces holding the particles together in a gas of every week allowing them to move around freely.
Can you draw a diagram showing the difference between the particles and solid liquids and gases
To draw such a diagram you would draw 20 circles divided up into five rows packed class together and then ordered rose
For the liquids you would show that the circles were not as packed together and we’re moving around a bit and for gases you would have fear particles much further apart. look at the picture in your book.
How do we make changes in the states of matter? (Will book this how can we induce changes to the state of matter)
Changes to the states of matter can be bought by by changing the temperature AND/OR pressure
For example increasing the temperature of a solid what causes particles to move around more and more eventually lead to a liquid state
Increasing the pressure on causes particles to become eventually leading to a liquid or solid state.
