Tungsten Copper Rod Density

Introduction

The mass of some substance per unit volume is called density of this material, which is a reflection of the physical properties of the material in physics. Tungsten copper rod density is a kind of feature itself, which does not change with mass or volume.

Measurement

Based on the principle of ρ=m/V, the measurements of tungsten copper rode density include weighing, pyknometer method, Archimedes' principle, floating method, densitometer method.
Weighing:
1. Weigh the mass of metal block by balance, record as m;
2. The amount of water injected into the cylinder, readout volume V1;
3. Get the block out and put the beaker on the balance and weigh out the beaker and the remaining water mass m3.

Application

1. Identify the components of the materials: The density of the measured density and density tables comparing various substances, so we can identify what the object substance is;
2. Calculate the content of the substances contained;
3. Calculate the mass or volume of the object, which has mass difficult to weigh and difficult shape: According to a variant form of the density formula: m = Vρ or V = m / ρ, can calculate the mass and volume of the object, especially some inconvenience to directly measure the mass and volume of the object;
4. Determine the object is solid or hollow;
5. Calculate the internal pressure and buoyance of fluid (density can be calculated cylinder pressure);
6. Identify the unknown substance: Calculate the gas density combined with spectral analysis confirmed that new gas.
