Kinetic Particle Theory Flashcards
Meaning of matter
Anything that has mass and takes up space
Meaning of particle
Building block of matter
Melting
The process by which a solid turns into a liquid at its melting point
Boiling
At which as liquid turns into a gas at its boiling point
Condensation
The process by which a gas turns into a liquid
freezing
The process by which a liquid turns into a solid
Sublimation
The process at which a solid turns directly into a gas without melting
Evaporation
The conversion of liquid to its vapour below the boiling temperature of the liquid
Deposition
When a gas turns directly into a solid
Kinetic Particle Theory states:
“All matter is made up of tiny particles that are in constant random motion and constantly collide with one another”
A scientific theory is?
A scientific theory is a well-substantiated explanation of some aspect of the natural world
Matters can be classified as…
- Solid
- Liquid
- Gas
Arrangement of particles in a solid
The particles of a solid are closely packed in an orderly pattern with very little space between them
Arrangement of particles in a liquid
The particles of a liquid are closely packed in a disorderly manner, with slightly more spaces between them than in a solid
Arrangement of particles in a gas
The particles of a gas are very far apart from one another in a disorderly manner
