Which Is Heavier: 1 Liter Of Water Or 1 Liter Of Ice

One of the most mysterious substances on the planet is water. And which of its states of aggregation is heavier with equal volumes: liquid water or ice? Heating radiators have the hottest water at the top. And in the ice drift, cold ice floats along the surface of the river.

The ratio of volume and mass of water

A liter is a unit of volume for liquid substances. It is permissible to measure in liters also granular substances with a sufficiently fine fraction. For other solids, the concept of a cubic meter (decimeter, centimeter) is used. The definition of the term and concept of the liter was formulated by the General Conference on Weights and Measures in 1901. The definition is as follows: 1 liter is the volume of one kilogram of pure fresh water at an atmospheric pressure of 760 mm Hg and a temperature of +3, 98 ° C. At this temperature, the water reaches its highest density.

Having crossed the temperature threshold of +3, 98оС, the density of water again begins to decrease, and at + 8оС again reaches the same values ​​as at zero.

Steam, water and ice are states of the same substance, the molecule of which contains two hydrogen atoms and one oxygen atom. The difference between liquid and solid water lies in the peculiarities of intermolecular structures. In a liquid substance, water has a higher density than in a solid.

Which is heavier?

If, for example, 1 kg of water is poured into any vessel, it will have a volume equal to one liter. If you freeze this water, then with the same mass of 1 kg, the water, freezing, will tend to take up more space in the vessel. A closed vessel, limited by a capacity of 1 sq. dm (1 liter), break the ice. It turns out that with the same mass of liquid and frozen water, the ice will have a larger volume, which will violate the initial condition.

If you freeze a 1 liter plastic bottle with 1,000 ml of water (1 liter), about 80 ml of water will pour out of it during the hardening process. And to get 1 liter of ice, it is enough to freeze 920 ml of water.

If we initially proceed from the equality of volumes, and the frozen water - a piece of ice - is limited by the dimensions of a cube with a side equal to 1 dm (1 l), then its mass will become less than the initial kilogram. How could it be otherwise if you cut and remove some of the ice, adjusting the cube to the specified volume. Therefore, water in the volume of a liter is heavier than ice in the same volume.

Freeze and restore

Today it is more and more difficult to find pure natural water. Especially in a city, where it is filtered, chlorinated, and subjected to other types of physical and chemical treatment before entering the apartment. Pure water is becoming scarce, the cost of water produced from artesian wells is growing. However, water, it turns out, restores its original structure and energy after freezing - it is purified. Therefore: drink melt water! It is not in vain that all plants react to it so well in the spring and animals drink with pleasure.
