States of Matter
This is the state of matter that has a definite shape and a definite volume.
What is a solid?
DAILY DOUBLE
You observe that a white powder and a clear liquid react and begin bubbling and releasing heat.
What evidence tells you this is a chemical change?
What are the formation of gas bubbles and the release of heat?
Cutting, tearing, or crushing something results in this type of change.
What is a physical change?
A combination of two or more substances that keep their own properties.
What is a mixture?
When heat is added to matter, the particles do this.
What is move faster?
This state of matter takes the shape of its container but has a definite volume.
What is a liquid?
A physical property that describes how well something lets heat or electricity pass through.
What is conductivity?
A change that forms a new substance is called this.
What is a chemical change?
A mixture where one substance dissolves completely in another.
What is a solution?
When heat is removed from matter, the particles do this.
What is slow down?
This state of matter has no definite shape or volume.
What is a gas?
The ability of a substance to dissolve in a liquid.
What is solubility?
Rust forming on a bike is an example of this type of change.
What is a chemical change?
That substance that does the dissolving in a solution is a solvent. True or False.
What is true?
Adding heat to a solid increases the space between particles; this process is called this.
What is expansion?
The process of a liquid changing into a gas.
What is evaporation?
The temperature at which a solid becomes a liquid.
What is the melting point?
Melting ice is this type of change because the particles stay the same.
What is a physical change?
DAILY DOUBLE
You mix salt into warm water and it completely disappears. Later, you boil the water away and the salt is left behind.
What type of change is this overall, and why?
What is a physical change? Because no new substance is formed and the salt can be recovered.
When particles lose heat and move closer together, this happens.
What is contraction?
The state change when a solid turns directly into a gas without becoming a liquid first.
What is sublimation?
The term for matter that allows light to pass through completely.
What is transparent?
Signs of this change may include bubbles, colour change, or heat being released.
What is a chemical change?
A method used to separate a mixture of sand and water.
What is filtration?
The particle model of matter says matter is made of tiny particles that do these three things.
What are:
