Definitions 1
Anything that takes up space and has mass
Matter
A state of matter with a definite volume and a definite shape
Solid
Matter that contains only one kind of particle
Pure Substance
True or false: All matter is made up of tiny particles
True
Is a black marker a pure substance or a mixture? How do you know?
Mixture - when water is added, you can see all the different dyes used
An explanation of what matter is made up of and how it behaves
The Particle Theory
A state of matter that does not have a definite volume or a definite shape, it takes the shape of its container
Gas
Matter that contains two or more pure substances mixed together
Mixture
True or False - The second part of the Particle Theory State that particles have empty spaces between them
True
Salt dissolves fastest in what temperature of water? Use the particle Theory to explain.
Hot Water - Particles spread further apart when heated
The study of Matter and its Changes
Chemistry
A mixture with different parts that you can see
Heterogeneous Mixture
A measure of the quality of space occupied by an object
Volume
What is the Third law or the Particle Theory?
Even though you cannot see them, particles are moving randomly all the time
When salt dissolves in water - where do the salt particles go? Use the Particle Theory to explain.
Particles have empty spaces beween them - the salt particels go between the water particles
The larger part of a solution; the part of a solution into which the Solutes Dissolve.
Solvent
The smaller part of a solution; the part of a solution that dissolves in the solvent
Solute
A mixture that looks like a single pure substance; a uniform mixture of two or more pure substances
Homogeneous Mixture
What is the Fourth Law of the Particle Theory?
Particles move faster and spread farther apart when they are heated.
What happens to the Mass of a solid when it is turned into a liquid? Use the particle theory to explain.
The mass of a solid does not change when converted into a liquid - Particles move farther apart when heated and therefore behave differently
All particles are the same type of Molecule
Compound
All particles are the same type of atom
Element
To mix one type of matter into another type of matter to form a solution
What is the Fifth Law of the Particle Theory?
Particles attract each other, so they tend to stay together rather than fly apart.
What happens when you place drops of food coloring in water without Stirring? Use the Particle Theory to Explain.
The food coloring and water particles mix together even without stirring because particles are moving randomly all the time.
