Sailboarding at the Summer Olympics See List of Olympic medalists in sailing#Sailboard class. Olympic sailboarders are included in . Sailboarding at the Summer Olympics Sailboarding or Windsurfing has been one of the Olympic sailing events at the Summer Olympics since 1984 for men and 1992 for women. All sailors use the same One Design boards, daggerboards, fins and sails. The equipment is chosen to allow racing in a wide range of sailing conditions, as during the Olympic Games events must take place as scheduled whether or not there is enough wind for planing. Multiple medal winners include Alessandra Sensini and Barbara Kendall with three medals;
Activity coefficient be adjusted for non-ideality by scaling partial pressures by a fugacity coefficient. The concept of activity coefficient is closely linked to that of activity in chemistry. The chemical potential, "μ", of a substance B in an ideal mixture of liquids or an ideal solution is given by where "μ" is the chemical potential of a pure substance formula_2 and "x" is the mole fraction of the substance in the mixture. This is generalised to include non-ideal behavior by writing when "a" is the activity of the substance in the mixture with where "γ" is the activity coefficient, which may itself
