John Gough (natural philosopher) wife and seven of their children. He was buried in the parish churchyard of Kendal. Gough had wide-ranging scientific interests. He published papers in natural history, mechanics, mathematics, chemistry, and experimental physics. One of his most interesting pieces of work was an investigation into the properties of natural rubber or Caoutchouc. He was the first to describe the heat released when a rubber band is quickly stretched, the heat being detected by the lips to which the band is pressed. When stretched rubber is heated, it contracts, a reversal of the normal behaviour of materials when heated. Gough published these
Amount of substance replaces the term "number of moles" which should no longer be used according to IUPAC recommendation. However, confusion can arise due to the everyday usage of the term amount and the term "enplethy" has been suggested for international usage to replace amount of substance. When amount of substance enters into a derived quantity, it is usually as the denominator: such quantities are known as molar quantities. For example, the quantity which describes the volume occupied by a given amount of substance is called the molar volume, while the quantity which describes the mass of a given amount of substance is
