The Particle Model Flashcards
(13 cards)
What is a property?
A characteristic that describes what a substance is like and what it does
Properties include attributes such as color, shape, and behavior under certain conditions.
What is a substance?
A material that has one type of matter
Substances have uniform properties and are distinct from mixtures.
What are examples of substances?
- Silver
- Sugar
- Pure water
Each of these substances has unique properties.
What is a mixture?
A material made up of two or more different substances
Examples include wood, soil, and most rocks.
Are all materials mixtures?
No, not all materials are mixtures; some have just one type of matter.
Substances are examples of materials that are not mixtures.
What is the particle model?
A way of describing matter in terms of particles (i.e., atoms and molecules)
This model helps to explain the properties and behaviors of different substances.
How many particles are in one grain of sugar?
About 1,000,000,000,000,000,000 particles
This illustrates the incredibly small size of particles.
What is matter made from?
Tiny particles
These particles can be atoms or molecules, depending on the substance.
True or False: All particles in a substance are the same as each other.
True
For example, all water particles are identical to each other.
What is the difference between silver particles and sugar particles?
They are different types of particles
Each substance has its own unique particle structure.
What does the structure of matter describe?
The arrangement and interaction of particles within different substances
This includes how particles are organized and how they behave.
What happens to water when a force is applied?
It flows
This is a property of liquids, demonstrating their ability to change shape.
What is the temperature at which the properties of the substances are described?
Room temperature (20 °C)
This is a standard condition for observing physical properties.
