LESSON 1: WHAT IS MATTER Flashcards
any physical substance that POSSESSES MASS and OCCUPIES SPACE (volume), setting it apart from other fundamental concepts in science
matter
amount of matter in an object (heaviness or lightness)
mass
amount of the EARTH’S GRAVITATIONAL PULL on a certain object
weight
more massive objects - more gravitational pull - _______
heavier
amount of SPACE an object OCCUPIES (big or small)
volume
- all matter is made up of tiny particles
- al particles of one substance are the same
- different pure substances are made of different particles
- particles are always moving
- there are attractive forces between particles
Kinetic Theory of Matter (Particle Theory)
the _____ between particles also affects strength of the interactive forces that each one of them experience
distance

5 PHASES OF MATTER
solid
liquid
gas
plasma
bose-einstein condensate
DENSLEY PACKED particles of matter, attractive forces are VERY STRONG, particles are in a FIXED position
SOLID
distance between particles is VERY HIGH, have LESS attractive forces, have the HIGHEST FREEDOM to move
GAS
it is produced when matter is COOLED to EXTREMELY LOW TEMPERATURE, achieved by cooling an object close to absolute zero.
BOSE-EINSTEIN CONDENSATE
WILLIAM CROOKES, gas particles tend to look like GLOWING JELLY at high temperatures
PLASMA
particles that are NOT AS DENSLEY PACKED AS SOLIDS, still exert attractive forces, has ability to FLOW
LIQUID
sublimation
solid to gas
