nonrenewable energy resources that form in the earths crust over millions of years from the buried remains of once living organisms
Term
Renewable Resouces
Definition
a natural resource that can be used and replaced over a relatively short time
Term
Insulation
Definition
a supstance that reduces the transfer of thermal energy
Term
Conduction
Definition
the transfer of thermal energy from one subtance to another through direct contact conduction can also occur withina subtance
Term
Convection
Definition
The transfer of thermal by the movement of a liquid or a gas
Term
Radiation
Definition
the transfer of energy through matter or space as electromagnetic waves such as visible light and infrared waves
Term
Tempature
Definition
a measure of how hot (or cold) something is specifically a measure of the average kinetic energy of the particles in an object
Term
Thermal Expansion
Definition
The increase in volume of a substance due to an increase in temperature
Term
Absolute Zero
Definition
the lowest possible temperature
Term
Heat
Definition
The transfer of energy between objects that are at different tempertures; energy is always transferred from higher-temperature objects to lower-temperature objects until thermal equilibrium is reached
