Particles Flashcards
If particles move rapidly and are very spread out
Gas
When heating up a substance, the particles begin to ________________and ____________.
When heating up a substance, the particles begin to spread apart and move faster.
The changes from a solid state to a liquid state is called ____________________.
The changes from a solid state to a liquid state is called melting.
How are particles in gases positioned?
Moving in all direction
How are particles in liquids positioned?
Closely packed
Which states of matter can flow?
Gases and Liquids
In which states of matter are attraction forces at its strongest?
Solids
You trap particles inside a syringe then push the plunger down.
There are the same amount of air particles in each syringe.
A tablespoon of salt is added to a glass of water. In this example, the salt is the
Solute
The expansion and contraction of a substance is caused by a change in ________________.
Temperature
What properties do all states of matter have in common with one another?
They don’t have anything in common
What happens to a substance when decrease its temperature?
Contracts
When particles are heated, what happens?
They have more energy
the particles are close together but randomly arranged. The particles can move over each other.
Liquid
What is between air particles?
Nothing
What will allow more solute to be dissolved in a solvent.
Heating the solution
Which would I need to mix salt with to create a solution?
Water
When liquid is heated up, it changes into a new ________________________ called gas.
State of matter
the particles are close together in a rigid form and vibrate continuously
Solid
How are particles in solids positioned?
Packed closer together
What happens to the particles when you “cool off” a substance?
Slow down or have less energy
What does it mean to be “Soluble” ?
Capable of being dissolved.
What does it mean to filtrate
To come through the funnel
What does it mean to be a residue
When the solid stays in the funnel
What does it mean to be Insoluble
That doesn’t dissolve
What does it mean to be Dissoluable
That it can dissolve
What is the solvent?
Is a liquid in which a solute dissolved to form a solution.
What is the solute?
A substance in which dissolves into a liquid to form a solution.
What is saturation
When we can’t dissolve an unlimited amount of solute into a solvent, eventually the solvent becomes saturated. This means that no more solute can dissolve
