Two-way Street?
Energy Movement
100
My molecules are loosely bonded allowing them to slide past each other.
What is a Liquid?
100
My particles are moving so slowly the human eye/brain cannot detect it, and are bonded securely to each other.
What is a Solid?
100
This happens when a liquids molecules slow down, get closer together, and become bonded to each other.
What is Freezing?
100
A change in the appearance of a substance or object.
What is a Physical Change?
100
Energy is absorbed by a substance leading to a change in state of matter.
What is Endothermic?
200
The result of gas molecules slowing down and getting closer together.
What is a Liquid?
200
The particles in this state of matter move very quickly, are spaced far apart, and are not bonded to each other.
What is a Gas?
200
Fog forms on the inside of a buses windows on a cold morning.
What is Condensation?
200
A new substance is formed.
What is a Chemical Change?
200
Energy is released by a substance leading to a change in state of matter.
What is Exothermic?
300
When energy is added to this state of matter, its molecules speed up and move apart allowing them to slide past each other.
What is a Solid?
300
The molecules of a liquids surface are bonded more tightly than the molecules on the inside, making droplets possible.
What is Surface Tension?
300
All substances have a temperature at which they will turn from a solid to a liquid.
What is Melting point?
300
You dye your hair purple.
What is a Physical Change?
300
Freezing food is an example of an _____________ reaction because the energy in the food is being removed.
What is Exothermic?
400
Examples of this type of solid are sugar, diamonds, and salt which have an orderly arrangement of molecules.
What is Crystalline?
400
Some liquids flow more easily or slower than other liquids based how easily their molecules slide past each other.
What is Viscosity?
400
Making Dry Ice from Carbon Dioxide gas.
What is Deposition?
400
Baking Soda reacts with vinegar and forms a gas.
What is a Chemical Change?
400
Particles in a substance are reacting to energy by moving faster and getting further apart from each other.
What is Endothermic?
500
This solid has a disorderly/unorganized arrangement of molecules.
What is an Amorphous solid? Examples?
500
State of matter where molecules are moving extremely fast, and a huge amount of energy is present.
What is a Plasma? Examples?
500
Liquid steel is molded into solid steel beams.
What is Freezing?
500
You fry an egg.
What is both a Chemical and Physical change?
500
In an Exothermic reaction, the particles in the substance reacts in these three ways.
