Complete range of wavelengths which light can have. These include infrared, ultraviolet, and all other types of electromagnetic radiation, as well as visible light.
Nurning mavjud bo'lgan barcha to'lqin uzunligidagi diapazonlari. U infraqizil, ultrabinafsha va elektromagnit nurlanishning boshqa barcha turlarini, shuningdek, ko'rinadigan nurni o'z ichiga oladi.
Density is the mass per unit volume of any substance. Its units are kilograms per cubic metre.
Zichlik har qanday moddaning hajm birligidagi massasiga aytiladi. U kilogrammning metr kubga nisbatida ifodalanadi.
An element is a substance composed of atoms with identical atomic number . The older definition of element (an element is a pure substance that can't be decomposed chemically) was made obsolete by the discovery of isotopes .
Atom raqamlari bir xil bo'lgan atomlardan tashkil topgan modda. Elementga berilgan avvalgi ta'rif (element bu kimyoviy bo'linmas toza modda) izotopning kashf qilinishi bilan o'z kuchini yo'qotdi.
An exothermic reaction between an oxidant and fuel with heat and often light.
Oksidlovchi va yoqilg'i o'rtasida issiqlik va yorug'lik ajralishi bilan boradigan ekzotermik reaksiya.
Compounds containing a carbonyl group bound to a halogen atom.
Karbonil guruhiga galogen atomi bog'langan moddalar.
Empirical formulas show which elements are present in a compound, with their mole ratios indicated as subscripts. For example, the empirical formula of glucose is CH2O, which means that for every mole of carbon in the compound, there are 2 moles of hydrogen ...
Empirik formulalarda modda qaysi element atomlaridan necha moldan tuzilganligini ko'rsatadi. Misol uchun, glyukozaning empirik formulasi CH2O bo'lib, bu formulaga ko'ra har 1 mol uglerodga 2 mol vodorod va 1 mol kislorod to'gri kelishini ko'rsatadi.
Intermolecular forces that exist between polar molecules. Active only when the molecules are close together. The strengths of intermolecular attractions increase when polarity increases.
Qutbli molekulalar orasidagi molekulalararo kuchlar. Molekulalar o'zaro yaqin joylashgan holatdagina faollashadi. Molekulalararo tortishish kuchi qutblilik oshishi bilan ko'payadi.
Concentration of a substance in a mixture measured as moles of the substance per mole of mixture. For example, the mole fraction of oxygen in air is about 0.21, which means that 1 mol of air contains about 0.21 mol O2.
Aralashma tarkibidagi birikmaning konsentratsiyasi bo'lib, birikma mollarining aralashma moliga nisbati bilan aniqlanadi. Misol uchun, havo tarkibidagi kislorodning mol ulushi 0,21 ga teng, buning ma'nosi 1 mol havo 0,21 mol O2 ni o'z ichiga olgan, ...
Composed of two or more substances, but each keeps its original properties.
Ikki yoki undan ortiq moddalardan tashkil topadi va bunda har bir modda asl xususiyatlarini saqlab qoladi.
Change of an element into a different element, usually with some other particle(s) and energy emitted.
Bir elementning boshqa elementga aylanishi, odatda bu jarayon turli xil zarracha(lar) va issiqlik ajralishi bilan boradi.
