the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
atomic mass
100
anything that has mass and takes up space
matter
100
good at moving heat or electricity
conductor
100
matter that is warm and less dense
convection
200
the movement of energy from warm to cool
heat energy
200
the number of protons in the nucleus of an atom, which determines the chemical properties of an element and its place in the periodic table.
atomic number
200
the amount of matter in an object
mass
200
when a liquid becomes a solid
freezing point
200
the process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material
conduction
300
the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.
potential energy
300
with a positive electric charge of +1e elementary charge and mass slightly less than that of a neutron.
proton
300
the average mass of an element
density
300
the temperature at which a given solid will melt.
melting point
300
the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles that cause ionization
radiation
400
Thermal energy is the energy that comes from heat. This heat is generated by the movement of tiny particles within an object. The faster these particles move, the more heat is generated.
thermal energy
400
with no net electric charge and a mass slightly larger than that of a proton. Protons and neutrons
nuetron
400
the amount of gravitational pull on an object
weight
400
substance changes from a liquid to a gas
boiling point
400
the quality of being hot; high temperature.
heat
500
Heat energy is the result of the movement of tiny particles called atoms, molecules or ions in solids, liquids and gases
heat energy
500
a stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids.
electron
500
matter is not created or destroyed
law of conservation of mass
500
a substance made by mixing other substances together.But not creating a new substance
mixture
500
solid to a gas directly without going through a liquid stage
