solid to gas
sublimation
solid
tightly packaged molecules that vibrate in place
gas
molecules moving freely
liquid
molecules combined into one object that is flowy.
conduction
Conduction is when heat moves from one object to another object through direct touch
convection
Convection is the process of transferring heat through air or liquid currents
Insulation
something that heat can not transfer to for example plasticb
radiation
Radiation is energy that moves from one place to another in a form that can be described as waves or particles
conductor
a material that allows energy to flow
what is hot
the flow of energy from a warm object to a cooler object.
what is cold
Cold is the presence of low temperature, especially in the atmosphere.
Strong force
this holds the nucleus together, keeping the protons and neutrons together
atomic mass
the mass of an atom
shells
The electrons in the outermost shell, determines bonding
valence electron
energy levels where the electrons are found
atoms
The building blocks of matter. Made up of protons, electrons, and newtons
element
A pure substance all the atoms have the same atomic number or number of protons
Atomic number
The number of protons and electrons found in an element
Nucleus
the center of an atom, it contains the protons and neutrons
Proton
particles that have a positive (+) charge
Neutron
Particles that do not have a charge and are neutral
Electron
Particles that have a negative (-) charge
