State of Matter
The definition of matter.
What is anything that has mass and takes up space?
A type of reaction where a NEW substance is formed. The new substance has different properties from those of the reactants.
What is chemical reaction?
True or False
Atoms/Molecules are destroyed in a chemical reaction.
What is true?
When water vapor becomes liquid water drops (like dew on grass).
What is condensation?
Flammability and toxicity are examples of this type of property.
What is chemical properties?
Copper, gold, oxygen are all examples of this.
What are elements?
Is dissolving sugar in your tea a chemical reaction or physical change?
What is physical change?
Ms. Kearns boiled water and steam was seen coming off the top. This is the two states of matter that was observed in this experiment.
What is liquid and gas?
Name 2 physical properties of matter that can be observed in matter.
Ms. Kearns will check.
The 2 subatomic particles in an atom.
What are protons and neutrons?
This is a chemical reaction that absorbs heat.
What is endothermic?
The temperature at which a substance changes from a solid to a liquid?
What is melting?
These 2 "temperature points" are the same.
What is melting point and freezing point?
True or False
Atoms are mostly empty space.
What is true?
Name 2 signs that a chemical reaction has occured.
Ms. Kearns will check.
This is the measurement of how tightly matter is packed together.
What is density?
This occurs when a few particles of water are moving fast enough to break free AT THE SURFACE and become gas.
What is evaporation?
In this process, matter skips the liquid state and goes from a solid to a gas.
What is sublimation?
Double Jeopardy
The materials that undergo a change in a chemical reaction.
What is reactant?
Double Jeopardy
The difference between reactants and products.
What is products are the new substance created in a chemical reaction?
Define the Law of Conservation of Matter.
What is matter cannot be created or destroyed, just changed.?
