Malunga nale Calculator
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.
Imibuzo ebuza rhoqo
Yintoni ifomula yoxinano oluphezulu?
Uxinzelelo lulingana nobunzima obuhlukaniswe ngobukhulu, ρ = m / V. Ukuphinda ucwangcise, ubunzima = ρ × V nobukhulu = m / ρ.
Iiyunithi zeziphi ezisetyenziswa yinkqubo?
Ngokungagqibekanga, igram kunye nesentimitha yesiqwenga (1 cm³ = 1 mL) inika uxinano kwi g/ cm³. Amanzi acocekileyo amalunga ne 1 g/ cm³, ngoko ke izinto ezinamanzi aphezulu afunda phezulu 1 kwaye zijikeleze ezantsi.
Ingaba izinto ziya kudada okanye zihlambuluke emanzini?
Uthelekiso loxinzelelo lwamanzi ≈ 1 g/cm³. Ezantsi apho ihamba (iglasi kwi 0.92, i-oak kwi 0.75), ngaphaya kwayo ihamba ngokukhululekileyo, kwaye ngaphaya kwayo ihla (i-aluminium 2.70, intsimbi 7.87). I-calculator ichaza ukuba yeyiphi imeko esebenza.
Ndiyiguqula njani i-g/cm³ ibe yi-kg/m³?
Ukuphindaphinda nge 1,000: 1 g/ cm³ ilingana ne 1,000 kg/ m³. Isixhobo sibonisa zombini, ngoko ke 2 g/ cm³ isixhobo sibonisa njenge 2,000 kg/ m³.
Ndifumana njani ubunzima bomzimba okanye ubukhulu endaweni yoxinano olukhulu?
Itshintshela "ukulungisa" kwisisindo okanye umlinganiselo. Isisindo yi ρ × V kwaye umlinganiselo yi m / ρ, ngoko ke isixhobo se 2 g/ cm³ esigcwalisa 50 cm³ sinesisindo se 100 g.
Ingaba ubunzima bomzimba butshintsha ngobushushu?
Encinci, ewe. Izinto ezininzi zikhula xa zishushu, ngoko ubunzima babo buhla kancinci xa ubushushu bunyuka. Umanzi awuqhelekanga - ubunzima obuphezulu bumalunga ne-4 °C - oko kukuthi kutheni umkhenkce udada kwaye amalwandle abanda ukusuka phezulu ukuya ezantsi.
