States of Matter
These are the 3 states of matter.
What are solid, liquid, and gas?
Melting changes a solid into this.
What is a liquid?
This type of change makes new substances from old ones.
What is a chemical change?
These are the substances that are made at the end of a chemical reaction.
What are products?
A chemical change that releases energy.
What is exothermic?
In this state of matter, particles move freely. They have mass, but no fixed volume or shape.
What is gas?
What is a gas?
This change does not result in a substance changing into something new.
What is a physical change?
These are the substances before a chemical reaction has taken place.
What are reactants?
A chemical change that absorbs energy.
What is endothermic?
In this state of matter, particles can only vibrate. They have mass, a fixed volume, and shape.
What is solid?
Depositing a gas changes it into this.
What is solid?
Cutting, shaping, and changing states are examples of this kind of change.
What is a physical change?
This is the reactant in the chemical reaction that makes toast.
What is bread?
The boiling point of water.
What is 100 degrees Celsius?
In this state of matter, particles can flow in a container. They have mass and a fixed volume, but no shape.
What is liquid?
This is a change directly from a solid to a gas.
What is sublimation?
Baking, burning, and oxidation are examples of this kind of reaction.
What is a chemical change?
These are the [two] reactants in a wood burning reaction.
What are wood and oxygen?
At this location, all substances will be in the form of a gas.
What is the surface of the sun?
No matter what state of matter a substance has, you can always measure this property.
What is mass/weight?
In between a substance's boiling point and melting/freezing point, it is this state of matter.
What is liquid?
This chemical change happens when oxygen combines with metals.
What is oxidation?
In this endothermic chemical reaction, oxygen and sugar/carbohydrate are produced from carbon dioxide and water.
These are five signs that a chemical change has happened.(name 3 or more)
What are change in color, change in temperature, smell, light, and bubbles?
