Properties Of Matter Flashcards
Formula for density, mass and volume
Mass=density×volume
Density=mass÷volume
Volume= mass÷volume
When is water it’s most dense
Water is most dense at 4°C (39°f)
Definition of matter
Anything that has weight and occupies up space
An atom is mainly composed of what 3 particles what charge do they carry
Protons(positive)
Electrons(negative)
Neutron(neutral)
A compound is created when?
When atoms of two or more different elements chemically combine EX water is a combination of hydrogen and oxygen
When matter is only composed of one atom it is called?
An element
What are 3 common properties of metal?
Malleability, ductility and conductivity
What compound is one of the most abundant?
Water H²O
What are these compound is CH4, C3H8, and C4H10
CH4=Natural gas
C3H8=propane
C4H10=butane
What is a mixture
molecules of different materials combined in a way that no chemical reaction takes place
What is a solution
Mixtures in which one substance is dissolved by another evenly, so the whole mixture is the same throughout (homogeneous)
2 parts of a solution, what are they and what do they do
Solute, it is dissolved
Solvent does the dissolving
Define brittle
Will not bend without breaking
Define ductile
Ability to be stretched or drawn into shape
Define malleable
Can be beaten,rolled or squeezed into shape
Define adhesion
Unlike molecules stick together
Define capillary action
Tendency for adhesive liquids to flow into tight spaces
Define surface tension
Surface skin forms on liquids due to cohesive forces
Define cohesion
Like molecules stick together
Define compressible and incompressible
Able to occupy smaller volume when forced by additional pressure
Can’t be compressed to reduce volume
Define diffusion
Are able to spread when not under containment
Solid to liquid is called
Fusion
Liquid to gas is called
Vaporization
Gas to liquid is call
Condensation
