Definitions
Anything that has mass or takes up space
What is Matter?
These particles may be found vibrating in place
What is the particles of a solid?
These tiny things make up all matter and are always moving
What are particles?
A combination of two or more substances where each part keeps its own properties.
What is a Mixture?
Saltwater
What is a solution?
A particular kind of matter with uniform properties
What is a Substance?
These particles may be tighter together but NOT uniform
What is the particles of a liquid
According to the particle theory, when you heat a substance, this happens to the movement of it's particles
What is they move faster?
In a solution, this part is the substance that gets dissolved.
What is the solute?
______ is the Solute and _______ is the Solvent in chocolate milk (mixture not pre made)
What is Chocolate syrup and Milk
Syrup = solute, Milk = Solvent
A state of matter that does not have a definite shape or a definite volume
What is a Gas?
This matters' shape and volume will stay the same unless heated up
What is a solid?
This particle theory idea explains why heating a material usually causes it to expand in size
What is particles move faster and spread farther apart when heated?
This type of mixture has particles large enough to see and separate easily, like trail mix or salad (2 names for it)
What is a mechanical mixture/heterogeneous mixture?
Orange juice with pulp
What is a mechanical mixture?
A state of matter that has a definite volume but NOT a definite shape
What is a Liquid?
This matters particles gain energy when heated
What is a solid, liquid, and gas?
When a solid becomes a liquid, the particles gain _____ to partially overcome their attractions. This specific process is called _______
What is Energy and Melting
When a solute fully disappears into a solvent and forms a uniform mixture, we say this happened
What is dissolving?
Pop/Soda
What is a solution
A substance that does the dissolving
What is a Solvent?
This happens to particles when the temperature is lowered
What is particles losing energy?
According to particle theory, the behaviour of particles depends on these three key factors
What are particle spacing, arrangement, and movement
This property helps you decide whether a mixture is a solution or a mechanical mixture by examining how evenly the particles are spread out.
What is particle distribution? OR "are the particles evenly mixed?"
When you pour melted butter with popcorn seasoning over popcorn, the butter acts as this part of the mixture, while the seasoning (like salt and cheese powder) acts as the other.
What is the solvent (butter/oil) and the solutes (seasoning particles)?
