Density measures how much mass is packed into a given volume: ρ = m / V. Rearranged, the mass of an object is m = ρ × V and the volume it occupies is V = m / ρ. This calculator lets you solve for any one of the three, entering the other two in whatever units you have — grams, kilograms, pounds and ounces for mass, and cm³/mL, litres or m³ for volume — and returns the density in both g/cm³ and the SI unit kg/m³ (1 g/cm³ = 1,000 kg/m³).
As a worked example, a 100 g object occupying 50 cm³ has a density of 100 / 50 = 2 g/cm³ (2,000 kg/m³) — a bit less dense than aluminium. Because pure water is very close to 1 g/cm³, the calculator also tells you whether a material floats: anything below about 1 g/cm³ floats, anything above sinks, and something right at 1 g/cm³ is neutrally buoyant. A built-in table lists common densities for comparison — ice 0.92, oak 0.75, water 1.00, aluminium 2.70, iron 7.87, lead 11.34 and gold 19.32 g/cm³.
Density is used to identify materials, check the purity of metals and gemstones, work out whether an object will float or sink, convert between the mass and volume of fuels and liquids, and calculate the load a structure or vessel must carry. Because it is an intensive property — independent of the amount of material — a small sample gives the same density as a large one, which is what makes it such a reliable fingerprint for a substance.
Mafunso ofunsidwa nthawi zambiri
Kodi ndi chiyani formula density?
Mtundu wa mpweya umakhala ndi mpweya wofanana ndi wa mpweya wa m'madzi, ndipo umakhala ndi mpweya wofanana ndi wa m'madzi, ndipo umakhala ndi mpweya wofanana ndi wa m'madzi.
Kodi mayunitsi zimenezi amagwiritsa ntchito?
Kuyambira, gramu ndi cubic masentimita (1 cm³ = 1 mL) amapereka density mu g / cm³. madzi oyera ndi zokhudza 1 g / cm³, kotero denser-kuchokera madzi zinthu kuwerenga pamwamba 1 ndi kusefukira pansi.
Kodi zinthu zimayenda kapena kugwa m’madzi?
Kuyerekeza kulimba kwake ndi madzi ≈ 1 g / cm³. pansi kuti izo zimayenda (mkuwa pa 0.92, oak pa 0.75), pa izo ndi neutrally kusefukira, ndi pamwamba pa izo kumadulidwa (aluminium 2.70, chitsulo 7.87). Calculator akunena kuti kachilombo ka ntchito.
Kodi ndingasinthire bwanji g / cm³ kuti kg / m³?
Kuwonjezera ndi 1,000: 1 g / cm³ ndi 1,000 kg / m³. Chida chikuwonetsa zonse ziwiri, choncho 2 g / cm³ chimawonekeranso ngati 2,000 kg / m³.
Kodi ndingapeze bwanji maselo kapena kutalika kwa zinthuzo pogwiritsa ntchito mfundo za kulemera kwa zinthuzo?
Kusintha "kupeza" ku maselo kapena kulemera. Maselo ndi ρ × V ndi kulemera ndi m / ρ, choncho zinthu za 2 g / cm³ zodzaza 50 cm³ zili ndi maselo a 100 g.
Kodi density amasintha ndi kutentha?
Mafuta ndi madzi ndi zinthu zosadziwika bwino, chifukwa zimakula pamene zimatentha, ndipo kuchuluka kwa madzi kumatsika pang’ono pamene kutentha kumakwera. Mafuta ndi zinthu zosadziwika bwino, chifukwa zimakula kwambiri pamene kutentha kwa madzi kumafika pa 4 °C, chifukwa chake madzi amadzimadzi amayenda m’madzi ndipo magombe amatentha kwambiri.
