Abstract
The invention relates to a liquid density measurement method, which is mainly used in experimental teaching in university and moderate speciality schools. The method comprises the following steps: measuring the mass m of a solid with the known volume v by using an electronic balance, wherein the solid is insoluble in liquid to be measured and the density of the solid is larger than that of the liquid to be measured; placing a container containing a liquid sample to be measured on the electronic balance, marking the reading of the electronic balance as m1, fixing one end of a filament, tying the other end of the filament with the solid with the mass m, soaking the solid in the liquid to be measured without touching the container, marking the reading of the electronic balance as m2, and figuring out the density of the liquid sample to be measured through the m, the m1, the m2 and the v. The method provided by the invention is simple, convenient, fast and high in measurement precision and is suitable for measuring the density of various kinds of liquid.
Description
Affiliated technical field
The present invention relates to a kind of liquid density measurement method, be mainly used in big, the experimental teaching of special secondary school universities and colleges.
Background technology
Density is a physical parameter of material, and common liquid density measurement method has: all there is the shortcoming that measuring accuracy is not high, measurement is numerous and diverse in these methods such as conventional method, density bottle method, densimeter method, buoyancy method, buoyancy aid method.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides a kind of liquid density measurement method, it can measure various density of liquid accurately and rapidly.
The technical solution adopted for the present invention to solve the technical problems is step 1: with electronic balance measure a known volume ν, be insoluble to testing liquid, its density is greater than the quality m of the solid of testing liquid density; Step 2: the container that will fill the testing liquid sample places on the electronic balance, and the electronic balance reading is m
1Step 3: an end of fine rule is fixed, and the other end hitches the solid that quality is m, and with this solid immersion in testing liquid, but do not contact with container, the electronic balance reading is m
2, solid stressed analysis is had:
In the formula, g is local acceleration of gravity; Step 4: the density that is got the testing liquid sample by (1) formula is:
In the formula, ν is the volume of solid.
The invention has the beneficial effects as follows: with electronic balance measure a known volume ν, be insoluble to testing liquid, its density is greater than the quality m of the solid of testing liquid density, and the container that fills the testing liquid sample is placed on the electronic balance, the electronic balance reading is m
1, an end of fine rule is fixed, the other end hitches the solid that quality is m, and with this solid immersion in testing liquid, but do not contact with container, the electronic balance reading is m
2, by
Can try to achieve the density of testing liquid sample, this inventive method simply, easily and fast, the measuring accuracy height, and be applicable to various fluid samples.
