Substance
A substance that consists of only one type of atom
Element
A substance containing atoms of two or more different elements chemically bonded together
Compound
A group of chemical symbols and numbers that represent the elements and the number of atoms of each element that make up a compound
Chemical formula
A decrease in a material’s volume when the temperature is decreased
Thermal contraction
An increase in a material’s volume when the temperature is increased
Thermal expansion
The transfer of thermal energy from a region of higher temperature to a region of lower temperature. Heat can also refer to the amount of energy transfer during this process
