Statement of changes in equityA statement of changes in equity and similarly the statement of changes in owner's equity for a sole trader, statement of changes in partners' equity for a partnership, statement of changes in shareholders' equity for a company or statement of changes in taxpayers' equity for government financial statements is one of the four basic financial statements. The statement explains the changes in a company's share capital, accumulated reserves and retained earnings over the reporting period.
Thermal expansionThermal expansion is the tendency of matter to change its shape, area, volume, and density in response to a change in temperature, usually not including phase transitions. Temperature is a monotonic function of the average molecular kinetic energy of a substance. When a substance is heated, molecules begin to vibrate and move more, usually creating more distance between themselves. Substances which contract with increasing temperature are unusual, and only occur within limited temperature ranges (see examples below).
