the transfer of energy by electromagnetic waves. Radiation
a material that transfers heat, electricity, or both easily. Conductor
a material that does not transfer, heat, electricity, or both easily. Insulator
a physical property that describes matter as a solid, liquid, or gas. State of matter
the physical change of matter from one state to another. Change of state
the changing a solid to a liquid. Melting
the withdrawal of heat to change something from a liquid to a solid. Freezing
the temperature at which no thermal energy can be removed from matter. Boiling
the changing of a gas to a liquid. Condensation
the spreading apart of the matter particles of an object when that object is heated. Thermal expansion
the total energy of all the particles in an object. Thermal energy
The amount of heat that must be absorbed or lost for 1 gram of a substance to change its temperature by 1°C. Specific heat
the change of a substance from a liquid to a gas; it that takes place at the surface of a liquid. Evaporation
