Vocabulary
A noticeably different form of the same substance
What is a phase?
The state of matter that has a fixed shape and volume.
What is a solid?
Molecules that need a higher temperature to phase change from liquid to gas are said to have this.
What is a strong molecular attraction?
These were not able to be compressed in a syringes
What are solids and liquids?
Temperature is a measure of hot and cold and also this.
What is average kinetic energy?
The energy an object has because its moving.
What is kinetic energy?
The state of matter that has a fluid shape and fixed volume.
What is a liquid?
Molecules that stay a gas even at very low temperatures are said to have this.
What is a weak molecular attraction?
When we watched an ice cube melt, its molecules did this.
What is losing freedom of movement?
A phase change happens when molecules of a specific substance experience this.
What is a change in their freedom of movement?
A group of atoms joined together in a particular way.
What is a molecule?
The state of matter where molecules move away from each other.
What is a gas?
In order to get molecules with a strong molecular attraction to change from a liquid to a gas you need to increase this.
What is their kinetic energy?
It took the water longer to evaporate than the isopropanol because of this science concept.
Why does water had a higher molecular attraction?
Transferring energy into a substance does this it it.
What is increases its kinetic energy? (or What is increases its freedom of movement?)
What is freedom of movement?
The state of matter where molecules move in place.
What is a solid?
In order to get molecules with a weak molecular attraction to turn from a gas to a liquid you need to do this.
What is decrease their kinetic energy?
What happens when water molecule gain kinetic energy?
Transferring energy out of a substance does this to it.
What is decreases its kinetic energy? (or What is decreases its freedom of movement?)
The pull between molecules.
What is molecular attraction?
The state of matter where molecules move around each other.
What is a liquid?
In class we read about liquid oxygen, in the article this substance was described to have a weaker molecular attraction than another common substance.
What is water?
This is why gallium metal can melt in someone's hand so easily.
What is a low molecule attraction?
In order for a substance to phase change, the change in kinetic energy has to overcome this.
What is the molecular attraction between molecules?
