A cordial is concentrated fruit-based syrup. In the undiluted state the syrup is very sweet, so it is designed to be mixed with predominantly with water (for example tap water, bottled water or soda water).ordials are popular throughout Australia, and come in a variety of flavours, including orange, lemon, blackcurrant, and lime, but vary according to the market in which they are sold. Cordials may or may not contain juice and/or sugar. Like any beverage, cordials should be used in moderation as part of a balanced diet.
2) kilogram (symbol kg) is SI unit of mass - decakilogram is a multiple of the unit (10 kg) , and ounce and pound are relics of the *coughcough* inappropriate imperial unit system . 3) a thermometer is used to mesure temperature. a cylinder is for volume, a ruler for length and a balance for mass.
As there are many units of mass and volume covering many different magnitudesthere are a large number of units for mass density in use.The SI unit of kilogram per cubic metre (kg/mÂ³) and the cgs unit of gram per cubic centimetre (g/cmÂ³) are probably the most common used units for density.ensity 2. density may be expressed in terms of weight density (the weight of the material per unit volume) or as a ratio of the. density with the density of a common material such as air or water. Measurement of density The density at any point of a homogeneous object equals its total mass divided by its total volume.
