HOW cubic meters per ton of water

Weigh the water jar

The liquid as well as any other substance that has a volume and mass.

Accordingly, dlyaya measuring its amount used and measures the amount of weight and measure.

To determine how much weight the liquid, which occupies a given volume, it is not necessary to weigh it, the more the possibility is not always the case.

A simple experiment

The volume of water usually measured in liters. Weigh 1 liter of distilled water is easy. This requires:
- electronic balance-
- Dimensional Utensil-
- banka-
- Water.
Distilled water can be purchased at the store,which sells auto parts and other products for motorists, as well as a pharmacy. The Bank is better to take a glass. Chemical glassware for experiments with water is not required. Weigh the empty jar. Pour into it exactly 1 L of water and re-weigh. Subtract the result from the first second. You will get plenty of water. And you will see that it is equal to 1 kg. If you water from the tap or from a well, it may weigh a little more due to dissolved salts. The error is usually negligible, and school experience the difference can be ignored.

Translate volume measures

Remember, what is 1L. It is equal to one thousand cubic centimeters, that is one cubic decimeter. In turn, in one cubic meter - one thousand cubic decimeters. To see this, to raise enough in the ratio 1 cubic m = 10 dm. What weighs 1 dm3, you have already calculated. Remember, what is the ton. It equals 1000 kg. That is a ton weigh 1 000 dm3 of water. It turns out that 1 cubic meter of distilled water would weigh exactly 1 ton.

other liquids

Distilled leading is a kind ofstandard, which can be used in weighing other things. It does not cost anything to turn the jar with water weights. Poured into it a certain amount of water, you'll know exactly how much it weighs, so you can take advantage of this "weights" and to work with mechanical weights. Calculate the ratio of the mass and volume of liquids other not so easy to get. You need to know one more value - density. It can find in the table of densities of various chemicals. Calculate the density of the formula = m / V, where m -? Mass, and V - volume. To find the weight must be multiplied by the volume density. The same equation can be calculated and the weight of 1m3 of water. The density of water is equal to 0.9982 g / cm ?, but in the calculations, which do not require very high accuracy, it is usually taken as 1 g / cm ?. Substituting this value into the formula, you get m =? * V = 1 g / cm? Cm3 * 1,000,000 = 1,000,000 g = 1000 kg = 1 ton.
In the same way one can calculate the mass andsolid, if it can not be weighed, but the volume can be measured and known, it is made of a substance. To calculate the body mass index, consisting of several parts, you can take an average density, but calculations will be a big error.
