Matter Flashcards
Why do we study matter?
To improve our life style and solve problems.
Mass
Measurement of the amount of particles something has.
Energy
The ability to do work and cause changes.
What does a food chain show?
The energy transferred which decreases a 10% each level.
How is matter transformed in a food chain?
Through biogeochemical cycles in which it is reused.
Kilocalories
Energy stored as biomass.
Metabolism
The way we process matter and the energy we consume. Some energy is transformed into heat.
Transformation Mass-Mass
Combustion and boiling.
Transformation Mass-Energy
Chemical Reactions
Types of energy
Wind energy (Kinetic energy from the wind), Electric Energy (Kinetic energy of electrons) and Nuclear Energy (Potential energy from atoms).
States of matter
Liquid, solid, gas, plasma and bose-einstein condensate.
Quantum states of matter
Plasma and Bose Einstein condensate.
Solid
Definite shape and volume. No space between particles, no kinetic energy, no compressibility and no ability to flow.
Liquid
No definite shape, fixed volume, some space between particles, some kinetic energy, compressible under extreme pressure and has the ability to flow.
Gas
No definite shape or volume, a lot space between particles as well as movement, compressible and flows.
Plasma (Ionized gas)
So much heat that the atom breaks apart and leaves a bunch of nucleus and electrons free.
Bose-Einstein (Super atom)
It exists at absolute zero because atoms stop behaving like a particle and behave like waves which causes an atom identity loss.
Endothermic changes of matter
Melting, Vaporization and sublimation.
Exothermic changes of matter
Freezing, condensation and deposition.
Solid to gas
Sublimation
