States Of Matter Flashcards
Condensing
The process of gas changing into liquid
Sublimation
The change of gas turning in to a solid without being a liquid
Evaporation
The change of liquid to gas
Freezing
The change of state from a liquid to a solid
Melting
Melting the change of state from solid to liquid
Boiling point
The temperature at which a substance boils at. The substance evaporates quickly.
Melting point
The temperature at which a substance melts at (solid into a liquid). A liquid can freeze at the same temperature.
Particle model
A description of the moving particles that make up all matter and how they behave. The model explains solids, liquids and gases
Fog
It is a visible mass consisting of cold water droplets or ice suspended in the air or the earths surface.
Expansion
Increase in size due to the movement of particles in a substance
Meteorologist
Scientist who use observation of the atmosphere to predict or explain the weather
The properties of a solid 3 examples
- Take up a iced amount of space
- Not able to be compressed
- Define shape cannot be changed easily
The properties of a liquid 3 examples
- Liquids take up a fixed amount of space
- Can not be compressed
- It’s shape is kept to the shape of the container
Properties of gas 3 examples
- It spreads unless kept in a container
- It diffuses and take up as much space as it can
- Can be compressed
Explain diffusion and give an example
Diffusion is the spreading out or movement of particles from a region of high concentration to a region of low concentration to create equilibrium
Example-a perfume/spray
Name a liquid that can be found in all three states at normal temperatures.
Water in the ocean, in the polar ice, and in the air as water vapour.
Example of solid to liquid and what it’s called
Melting- ice cubes into a liquid
Example of gas to liquid what it’s called
Condensation- having a cold drink on a hot day as it “sweats”
Example of liquid to solid what it’s called
Freezing-water yo ice cubes
Example of solid to gas what it’s called
Sublimation-dry ice
Name three substances that have a melting point greater than the comfortable room temperature
Aluminium-660
Iron-1535
Table salt-804
What are the units of measurements for volumes of liquid?
1ml= 1cm3 1l= 1000cm3 1000l= 1m3
When heat was applies to a metal ring why could the ball easily fir through. Particle model?
As the metal ring was heating the particles inside the solid was expanding. Allowing the particles to move faster create an increase in the distance between the particles and the attraction between the particles decreases causing the inner radius increased in size so the ball could fit through the ring easily
Explain how particles behave when heated is applied.
When heat is applied to particles:
- particles move faster
- distance between particles increase
- the attraction between the particles decreases
Explain how particles behave when cooled
When heat is removed the particles contract:
- particles move more slowly
- distance between particles gets smaller
- the attraction between the particles increase
Explain how clouds are formed
Clouds are formed by tiny droplets of water, kept up by air currents.
Inter particle space
The space between the particles within a solid liquid or gas
What is the core temperature of the human body?
36-37
Diffusion
The spreading of one substance through another due to the movement of their particles
