The density of mercury is 13.6 × 10 cubic meters. If half a bottle of mercury is poured out, what is the density of the remaining mercury?

The density of mercury is 13.6 × 10 cubic meters. If half a bottle of mercury is poured out, what is the density of the remaining mercury?

The density of residual mercury is still 13.6 × 10 ﹥ kg / m ﹥ 179

Water, mercury, alcohol, density comparison

Mercury: 13.6 × 10 ^ 3kg / m ^ 3
Water: 1.0 x 10 ^ 3kg / m ^ 3
Alcohol: 800 kg / m3
If mercury > water > alcohol are mutually soluble, there are two layers, the mercury layer below and the alcohol and water mutually soluble layer above

The density of sea water is 1.03 * 1000kg / M & sup3; and the atmospheric pressure on the sea surface is 77cm Hg?
A physics problem, big problem Oh, to process!

One atmosphere is 76cm Hg
The pressure at the depth of 30m below sea level = 30m seawater pressure + 1cm mercury column pressure
Let's do it by ourselves

What is the dry density of 300-1200kg / M & sup3?

Dry density is the density of a material when there is no water in its pores
For example, the dry density of soil is usually 1400 ~ 1700kg / M & sup3;;
The dry density of wood is usually 283 ~ 1128kg / M & sup3;, the smaller is Paulownia density, the larger is Corbicula density

There is a kind of "horse flying swallow" craft work, which is made of alloy material with density of 8.0 × 10 & sup3; kg / M & sup3;, the volume () DM & sup3;, and the mass () kg of the craft are measured. If the mass of a "horse flying swallow" woodcarving handicraft of the same size is 600g, the density of the woodcarving wood is () kg / M & sup3
The craftsman completely immersed the handicraft in a container full of water and discharged 1kg of water

There are not enough conditions to get the answer

What is the density of water__ Kg / m ^ 3 (i.e__ G / cm ^ 3)__ The physical meaning is__

The density of water is 1000kg / m ^ 3 (i.e. 1.0g / cm ^ 3), which means 1000kg / m3. The physical meaning is that the mass of water per m3 is 1.0x10 cubic kilogram

What is the unit of density kg / M? For example, g / cm, kg / cm, g / M

If it's kg / m ^ 3, g / m ^ 3 will change kg into G, that is to say, multiplying by 1000 m ^ 3 is the same. Don't worry about it. If it's kg / m ^ 3, g / cm ^ 3 will change kg into G multiplied by 1000, and m ^ 3 will be changed into cm ^ 3, 1m ^ 3 = 1000000 cm ^ 3. Note that cm ^ 3 is in the denominator position, so we should △ 1000000 to sum up, multiply by 1000

The density of iron is 7.9 × 10 kg / M = g / cm
Fill in the blanks

The density of iron is 7.9 × 10 ^ 3 kg / M = 7.9 g / cm

The basic unit of density is____ The symbol is____ Sometimes the unit of density is also used___ The symbol is____ ,1g/cm³=____ kg/m³

① The density of water is 1.0 × 10 ~ (- 179); kg / M ~ (- 179;), which means_____ What is the meaning of______ The density of pure water is_______ g/cm³.
② In density unit, 1g / cm & # 179; =_________ When the mass of an apple is 171 g and the volume is 180 cm, the density of the apple is 0_______ kg／m³.

① The density of water is 1.0 × 10 ~ (- 179) kg / M ~ (- 179), which is read as one point zero times ten to the third power of kilogram per cubic meter,
The mass of water is 1.0 × 10 kg. If the unit is g / cm, the density of pure water is 1g / cm
② In the unit of density, 1g / cm & # 179; = 1 × 10 & # 179; kg / M & # 179
When the mass of an apple is 171 g and the volume is 180 cm, the density of an apple is 0_______ kg／m³
171÷180=0.95 g/cm³= 0.95×10³ kg/m³
