P
palladiy– platina guruhiga kiradigan noyob metall element, kumush-oq, po'stlog'li va yumshoq, platinadan ko'ra osonroq va birlashtirilishi: asosan katalizator va stomatologik va boshqa qotishmalarda ishlatiladi. Ramz: pd; atomi og'irligi: 106.4; atom raqami: 46; o'ziga xos tortishish: 12 ° c dan 20 ° c gacha.		palladium– a rare metallic element of the platinum group, silver-white, ductile and malleable, harder and fusing more readily than platinum: used chiefly as a catalyst and in dental and other alloys. Symbol: pd; atomic weight:106.4; atomic number: 46; specific gravity: 12 at 20°c.
parafin qatori– metan, ch4 yoki etan, c2h6 kabi umumiy formulaga ega c n h 2n + 2 ga ega bo'lgan to'yingan, alifatik uglevodorodlarning homolog seriyali.		paraffin series– the homologous series of saturated, aliphatic hydrocarbons having the general formula c n h 2n+2 , as methane, ch 4 , or ethane, c 2 h 6 .
parchala(ni)sh– atom yadrosining engil atomlarning yadrosiga bo'linishi, energiyaning chiqishi bilan birga bo'ladi.		fission– the splitting of the nucleus of an atom into nuclei of lighter atoms, accompanied by the release of energy.
