a law defining the relationship between pressure, volume, temperature and moles of a gas. Formula definition: pV = nRT (Pressure in Pa, volume in m3, n in moles, R is the Universal Gas Constant (8,31 J.K-1.mol-1), and temperature in Kelvin).
the Celsius temperature at which the volume of the gas is zero.
a bond formed when non-metal atoms share a pair of valence electrons to form a molecule.
electrochemical cells. Electricity is produced from chemical reactions in the cell.
