faollashtirish quvvati –reaksiyani boshlash uchun zarur energiya. Misol uchun, o't o'chirish qurilmasining sig’masidan olov kamroq energiya beradi, undan keyin portlovchi reaksiya o'z-o'zidan ketadi, bu esa juda katta miqdordagi energiya chiqaradi. Turg'un, lekin eng og'ir obyektga berilgan kichkina jismning tushishiga olib kelishi mumkin; tushishda tarqalgan potentsial energiya tizimida obyekt tik va muvozanatli.
activation energy– the energy required to initiate a reaction. For example, the flame from the fuse of a firecracker provides a small initial amount of energy, after which the explosive reaction proceeds by itself, releasing a considerably larger quantity of energy. A small push given to a stable but top-heavy object may cause it to fall over; the potential energy released during the fall was present in the system all along but could not be realized as long as the object was upright and balanced.
faza – har qanday moddaning yoki holatning bir narsasi ko'zga yoki aqlga namoyon bo'ladigan asosiy ko'rinish yoki jihatlardan biri		phase – any of the major appearances or aspects in which a thing of varying modes or conditions manifests itself to the eye or mind.
fenol–bundan tashqari, karbolik kislota, gidroksibenzen, oksibenzen, fenik kislotasi ham deyiladi. Oq, kristal, suvda eriydigan, zaharli massa, C6H5OH, ko'mir qatroni yoki benzolning gidroksil lotinidan olingan: asosan antiseptik va organik sintez sifatida dezinfeksiya qiluvchi vosita sifatida ishlatiladi		phenol–also called carbolic acid, hydroxybenzene, oxybenzene, phenylic acid. a white, crystalline, water-soluble, poisonous mass, C 6 H 5 OH, obtained from coal tar, or a hydroxyl derivative of benzene: used chiefly as a disinfectant, as an antiseptic, and in organic synthesis
fenolftalein– oq, kristalli birikma, C 2 0 H 4 O 4, kislota-asosli titrlashdagi indikator sifatida va laksatif sifatida ishlatiladi.		phenolphthalein– a white, crystalline compound, C 2 0 H 1 4 O 4 , used as an indicator in acid-base titration and as a laxative.
fenolga oid– fenol yoki fenol sexi bilan kontsentratsiyasi natijasida hosil bo'lgan termoset qiluvchi reçinelerin har qanday turi, ayniqsa aldehit, ayniqsa formaldehit bilan: asosan bo'yoq va plastmassa ishlab chiqarishda va zımpara va kontrplak uchun yopishtiruvchi sifatida ishlatiladi.		phenolic– any of the class of thermosetting resins formed by the condensation ofphenol, or of a phenol derivative, with an aldehyde, especially formaldehyde: used chiefly in the manufacture of paints and plastics and as adhesives for sandpaper and plywood.
