Heat capacity system. When expressing the same phenomenon as an intensive property, the heat capacity is divided by the amount of substance, mass, or volume, thus the quantity is independent of the size or extent of the sample. The molar heat capacity is the heat capacity per unit amount (SI unit: mole) of a pure substance, and the specific heat capacity, often called simply specific heat, is the heat capacity per unit mass of a material. Nonetheless some authors use the term specific heat to refer to the ratio of the specific heat capacity of a substance at any given temperature to
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
