Alcohol by volume

Alcohol by volume (abbreviated as ABV, abv, or alc/vol) is a standard measure of how much alcohol (ethanol) is contained in a given volume of an alcoholic beverage (expressed as a volume percent). It is defined as the number of millilitres of pure ethanol present in 100 millilitres of solution at 20°C. The number of millilitres of pure ethanol is the mass of the ethanol divided by its density at 20°C, which is 0.78924 g/ml. The ABV standard is used worldwide. The International Organization of Legal Metrology has tables of density of water–ethanol mixtures at different concentrations and temperatures.

In some countries, alcohol by volume is referred to as degrees Gay-Lussac (after the French chemist Joseph Louis Gay-Lussac), although there is a slight difference since Gay-Lussac used 15 °C.

Mixing two solutions of alcohol of different strengths usually causes a change in volume. Mixing pure water with a solution less than 24% by mass causes a slight increase in total volume, whereas the mixing of two solutions above 24% causes a decrease in volume. More information on the phenomenon of volume changes due to mixing dissimilar solutions is discussed in the article on partial molar volume.

ABV (TV station)

ABV is the Australian Broadcasting Corporation's television station in Melbourne, Victoria. The station began broadcasting on 19 November 1956 and is transmitted throughout the state via a network of relay transmitters and also ABV is the second television station in Victoria with HSV-7 which opened at the same month of 1956 as the first TV station in Victoria. The studios are located in Southbank and Elsternwick, and transmitter at Mount Dandenong.

Programming

Local programming

ABV follows a schedule nearly identical to that of other statewide ABC Television stations, allowing for time differences and some local programming - including news, current affairs, sport and state election coverage.

ABC News Victoria is presented by Ian Henderson from Monday to Thursday and Tamara Oudyn from Friday to Sunday. The weeknight bulletins also incorporate weather forecasts presented by Paul Higgins as well as a national finance segment presented by Alan Kohler. The main fill-in presenters are Guy Stayner, Frances Bell and Beverley O'Connor with Vanessa O'Hanlon from ABC News Breakfast as the main fill in weather presenter.
