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
There is the least kinetic energy in
The Solid Phase
What are the 3 states of matter?
Liquid, Solid & Gas
