Heat capacity properties are often prefixed with the term "specific". International standards now recommend that specific heat capacity always refer to division by mass. The units for the specific heat capacity are formula_7. In chemistry, heat capacity is often specified relative to one mole, the unit of amount of substance, and is called the molar heat capacity. It has the unit formula_8. For some considerations it is useful to specify the volume-specific heat capacity, commonly called volumetric heat capacity, which is the heat capacity per unit volume and has SI units formula_9. This is used almost exclusively for liquids and solids, since
Notional amount inverse exchange-traded funds, have the unusual property that their notional changes every day: this is because they pay the compounded daily return, so it is as if one were re-investing each day's earnings at the new daily price: if one has an inverse ETF in an asset that goes down, one has more money, which one uses to short a cheaper asset, hence one's unit notional goes up, and conversely if the asset has gone up in value. See inverse exchange-traded fund for mathematical details. Notional amount The notional amount (or notional principal amount or notional value) on a financial
