Basics of Chemistry Eg.What is Matter (Very Basics) Flashcards
What is Matter
Anything that has mass and volume
What is Volume
Its the amount of space taken up by a substance, measured in mL, L, or cm3
What is Mass
Its the amount of matter, measured in grams or kilograms
Solid has a
Fixed Shape & Fixed Volume
Liquid has a
Shape that depends on the container & Fixed Volume
Gas has a
No fixed Volume & Shape depends on its surroundings
The KMT stands for
Kinetic Molecular Theory
What does the KMT say about particles (3 things):
- All matter is made of very small particles, called atoms or molecules
- There is empty space between particles
- Particles are constantly moving
How much can solid, liquid and gas particles move
Solid: Particles can only vibrate
Liquid: Particles can only slide past each other
Gas: Particles can move around freely
Different Transformation of States
Melting, Evaporation, Condensation, Solidification, Sublimation & Deposition
Melting = Solid to Liquid Evaporation = Liquid to Gas Condensation = Gas to Liquid Solidification = Liquid to Solid Sublimation = Solid to Gas Deposition = Gas to Solid
What is Melting and Boiling Point
Meting Point = A specific temperature where a solid turns into a liquid
Boiling Point = A specific temperature where a liquid turns into a gas
When you add energy to matter, its temperature ______
rises
When you remove energy from particles they move _______ and the matter __________
slower Contracts
What happens to matter when energy is added to it
the particles move around faster
There is the most kinetic energy in
The gas phase
