yuza tarangligi –suyuqlik yuzasida mavjud bo'lgan moslashuvchan kuch, xususan suyuqlik, sirt molekulalari orasidagi molekulyar kuchlar assimetrlari tomonidan yuzaga keladigan sirtni kamaytirishga intiladi.
surface tension –the elasticlike force existing in the surface of a body, especially a liquid, tending to minimize the area of the surface, caused by asymmetries in the intermolecular forces between surface molecules.
yuzada faol modda –suvda yoki suvli eritmada eritib yuborilganda uning sirt tarangligini yoki boshqa suyuqlik orasidagi intervalli kuchlanishni pasaytiradi.		surface-active agent –any substance that when dissolved in water or an aqueous solution reduces its surface tension or the interfacial tension between it and another liquid
Z
zahar–hayotni yo'q qilish yoki sog'lig'iga putur yetkazadigan tabiiy xususiyatga ega modda.		poison –a substance with an inherent property that tends to destroy life or impair health.
zang –bundan tashqari, temir zang deb ataladi. oksidlanish natijasida hosil bo'lgan temir gidroksid va temir oksiddan tashkil topgan havo va namlikka ta'sirlanganda temir sirtida yuzaga keladigan qizil yoki to'q sariq qoplama.		rust –also called iron rust. the red or orange coating that forms on the surface of iron when exposed to air and moisture, consisting chiefly of ferric hydroxide and ferric oxide formed by oxidation.
zanjir –odatda, bir-biridan o'tib ketadigan metall uzuklar shaklida, bir-biri bilan bir-biriga bog'langan bir qator ob'ektlar yoki turli maqsadlar uchun, masalan, yuk ko'tarish, qo'llab-quvvatlash, yoki cheklash yoki tortishish uchun, turli xil bezak va bezak shakllari.		chain –a series of objects connected one after the other, usually in the form of a series of metal rings passing through one another, used either for various purposes requiring a flexible tie with high tensile strength, as for hauling, supporting, or confining, or in various ornamental and decorative forms.
