A substance with a fixed volume and a fixed shape because the particles are packed tightly together and only shake or vibrate.
What is a solid?
100
This change in state occurs when a solid turns to a liquid.
What is melting?
100
This object undergoes sublimation when at room temperature.
What is Dry Ice?
What is solid CO2
100
These molecules combine to form polymers.
What is a monomer?
100
This substance is the main source of fuel for your body.
What is glucose?
200
This is a substance with a fixed volume but no fixed shape because the particles are free to move around one another.
What is a liquid?
200
This change occurs when a liquid changes to a solid.
What is freezing?
200
In the morning, water vapor undergoes deposition changing into this solid substance.
What is frost?
200
A substance that is able to be molded or shaped.
What is a polymer?
200
These are the most abundant molecules in your body.
What are water molecules?
300
A substance with no fixed volume or shape because the particles are moving very fast and spread apart to fill all the space available to them
What is a gas?
300
This change occurs when a liquid turns into a gas.
What is vaporization?
300
When water is in an environment with low temperatures, it does this.
What is freezes?
300
This is a natural polymer that can be made to be ultra-durable and comes originally from trees.
What is rubber?
300
These speed up chemical reactions in the human body.
What are enzymes?
400
A substance with more energy than a gas and has the atoms stripped of their electrons. Typically occurs at very high temperatures and pressures such as what
occurs inside stars. Most common state of matter.
What is plasma?
400
This change occurs when a gas turns to a liquid.
What is condensation?
400
You want to boil some water to turn it into a gas. You stove must be at this temperature to do so.
What is 212 degrees Fahrenheit or 0 degrees Celsius?
400
This is the process of making rubber more substantial against intense temperatures.
What is vulcanization?
400
Fats, oils, and cholesterol are all examples of this.
What is a lipid?
500
This determines how fast particles move. The higher the temperature, the more of this particles have. I basically determine states of matter.
What is kinetic energy?
500
There are two other physical changes.
1. When a solid turns directly into a gas.
2. When a gas turns directly in to a solid.
1. What is sublimation?
2. What is Deposition?
500
This is the only natural occurrence of plasma on earth.
What is lightning?
500
This was the first synthetic polymer invented by Leo Baekeland.
What is Bakelite?
500
This element plays an important role in the chemistry of living things, and because of its unique electron configuration, can combine in many ways with itself and other elements.
