100
Anything that has mass and takes up space (volume).
What is matter?
100
The theory that explains how particles act when energy is added or removed.
What is the Kinetic Molecular Theory?
100
A characteristic of matter that can be observed without changing its chemical identity.
What is a physical property?
100
Chemistry (definition)
What is the study of matter and its physical & chemical properties?
100
In the "Elephant Toothpaste" lab, two signs that a chemical change had occurred.
What are change in temperature and creation of gas.
200
The amount of material that makes up an object.
What is mass?
200
When you add energy to matter its temperature rises. Volume of matter increases when this happens.
What is expansion?
200
This can be separated into parts by physical changes.
What is a mixture?
200
The resource that tells you about all the known pure substances in the world.
What is the Periodic Table of Elements?
200
In the "Modeling Particle Size" lab, why did the volume of ethanol and water become less when you mixed them together?
The ethanol's particles were smaller than the water particles, so fit in the spaces between the water particles.
300
The amount of space that a material makes up.
What is volume?
300
Particles are spaced very far apart and can move freely.
What is a gas?
300
This is a pure substance that can be broken down into two or more elements by chemical changes.
What is a compound?
300
The number of protons and electrons in an element.
What is the Atomic Number tell you?
300
The three changes of state (in order) the water went through during the "Can Crush".
What are: Liquid (in the bottom of the can, Evaporation to water vapour (when the can was heated) Condensation back to liquid when the can was cooled
400
Particles are packed closely together and can only vibrate.
What is a solid?
400
Particles are spaced a bit further apart and can slide past each other.
What is a liquid?
400
A pure substance that can not be broken down by physical or chemical changes.
What is an element?
400
When particles slow down, and take up less space, as a matter's temperature decreases.
What is contraction?
400
The force that caused the can to crush.
What is air pressure.
500
Change from solid directly to gas?
What is sublimation?
500
Change from gas directly to solid.
What is deposition?
500
Give an example of each type of pure substance.
What is a compound - H20? What is an element - Gold ?
500
In the "Chromatography Lab", the substances in the ink were separated by putting them in water. What type of matter is ink?
Ink is a mixture because it can be changed without a chemical reaction.
500
Something that speeds up a reaction. (Give an example).
What is a catalyst. Yeast in the elephant toothpaste lab.
