But do you really know how much a liter of a kilogram?

question of how much a kilo in 1 liter, may seem rather silly ignorant man."Of course one!"- He said.And it makes a mistake.We used to think that if a measure of the weight of the solid (or bulk) of the substances measured in kilograms, the liquid - in liters.But it is not.Liter - a measure of the volume of liquid.It is only a cubic meter.It's a measure of the scope of solids - wood, for example.That is, a conventional cube, each face of which is equal to 10 cm. Of course, no one comes to mind to compare with kilo meter!

However (according to the law of Archimedes) volume is directly related to weight.So the question is: "How many kilograms per liter?" Not so idle.You just need to take account of another measurement parameter, namely the density of the material in this volume is inserted.The higher the score, the greater the weight of the substance will be.We recall the experience that we have demonstrated in the second grade at the lesson of natural history.Two empty cans put on the same scales.Under one of them lit a candle.The fire heats the air density is thus decreased.Bank of cold air becomes heavier.

You could tie the volume and weight, if every day to drink more water per liter of the daily value, then after a while you can lose two kilograms of weight.That is the conclusion drawn by researchers of the Technological Institute of Virginia, based on research.But how to calculate how many kilograms per liter?According to a simple formula: the weight is equal to density times the volume.What does this leave us in a residential area?We do not know, for example, the density of sour cream or honey.Moreover, this figure is very fickle, because it depends on weather conditions, even!

Yes, the density of the material can vary with temperature, humidity and atmospheric pressure.As a result, it will affect how much a kilogram per liter.Consider another experience from a school science: hot body increases in volume.Oh, and the sealed bottle full of water could burst if put it into the cold.In the context of the kitchen is good to have special measures.It looks like a normal pitcher.However, at the walls of the crockery has marks indicating the level of kilograms of sugar, vegetable oil, flour and milk.

Going on the market and asking the price of products to gardeners gardeners, which is usually sold in jars, we often wonder how many kilograms of fruit per liter.For here, in addition to the density of most "Kalinka-Malinka" play the role of other factors.For example, the number of gaps between the berries.That is, the larger the fruit, the more air you sell the bank.Thus, in a liter contains 600 g raspberries or blackberries, 800 g of cherries and bilberry, gooseberry 850 g 550 g cranberry and only 400 g of strawberries.

Well, how much kilogram per liter of water?In 1901, the Third General Conference of standard measures found that a liter of water is equal to a kilogram only if:

  • liquid distilled;
  • its temperature - 3.98 degrees Celsius;
  • atmospheric pressure in this case is 760 mm Hg.

If any one of these parameters is broken and does not coincide with the other, the weight of a liter of water is obtained less than one kilogram: at zero temperature, it weighs 999 grams, at 35 degrees Celsius - 994 g, at 90 degrees - 965
