A za'a fadada ma'ana, wadannan kaddarorin faye hali duka ba sinadaran Properties daga cikin abubuwa, Ina nufin irin wannan cewa abu ne muhimmi sabõda da hulda da sauran abubuwa.

Wadannan sun hada da kaddarorin kamar narkewa da kuma tafasar sigogi da yawan zafin jiki, zafi iya aiki da kuma thermal watsin, yawa abu. By electrophysical Properties ne inductance, thermal watsin da dielectric akai. Muhimmanci sosai ne da kaddarorin kamar sha, launi, taro.

A mafi muhimmanci yanayin fahimtar da jiki Properties da kuma halaye na cewa yankin, abin da suka gani, ya buga da cewa wani abu zai iya zama chemically tsaka tsaki da kuma barga kawai a cikin akwati inda barga shi ne tsarin da abun da ke ciki na ta kwayoyin. Wannan yana da muhimmanci, domin, ko da kasancewa a cikin wannan jiha na tari, da jiki Properties na wani abu na iya zama daban-daban. Wadannan bambance-bambance ne qaddara da dama yanayi, kamar crystal raga tsarin, gano shi a matsayin wani ɓangare na wani bayani, da sauransu.

Ba tare da togiya, duk abubuwa samu a cikin yanayi mallaka jiki Properties, wanda ƙayyade da rawar a cikin halitta tafiyar matakai. Alal misali, da narkewa yanayin zafi (wannan dukiya ne sau da yawa kawo sunayensu a matsayin nassoshi a cikin solidification zafin jiki), ita ce iyakar da yawan zafin jiki a wadda m crystalline jiki iya wuce a cikin ruwa a jihar. A wannan definition, yana da muhimmanci a fahimci cewa key kalma ne da kalmar "may", wato, shi yana nufin cewa a ba da zazzabi, da kayan iya zama ko dai ruwa ko m. Amma idan wannan zafin jiki kara da ɗan, da abu, ba shakka, da ke cikin wani ruwa jihar, kuma saboda haka - a kan m. Wannan jiki halayyar da abu ne a hankali related to wani dukiya - tafasasshen batu, amma wadannan kaddarorin ne m kawai a cikin yanayin lõkacin da ta je da tsarki abu.

Idan muka yi la'akari da jiki Properties kamar lantarki watsin, lantarki watsin, alaka da sub-rukuni na electro, ya kamata a ce cewa wadannan kaddarorin fahince jikin mutum ta ikon wuce ta lantarki a halin yanzu. Dangane da wannan, wadanda jikinsu wanda gudanar da wutar lantarki ake kira conductors, yayin da waɗanda ba su rasa - dielectrics. Bisa ga jiki halaye na bayanai, za mu iya nan da nan gama sinadaran Properties. Y conductors ne ko da yaushe free dako na wutar lantarki, amma wannan dielectrics iya ba su da. Wannan sanarwa take kaiwa zuwa ƙarshe da cewa jiki Properties da kakkarfan dangankata da kaddarorin sunadarai, kuma suka yi yardatayya sa juna.

Da taimakon jiki sigogi za a iya bayyana a matsayin wata babbar lamba na abubuwa da kuma abubuwa cewa kewaye da mu a yanayi. Alal misali, ainihin jiki Properties na nitrogen - wani abu wanda shi ne babban bangaren na iskan da muke shaka ne kamar haka.

Nitrogen ne a colorless iskar gas, wanda yana da narkewa zafin jiki daidai -210 ° C, da kuma a zazzabi da -196 ° C, nitrogen tafasa. Nitrogen ne mai narkewa a cikin ruwa da kuma ta yawa ne 0.0012506 g / cm3. A dielectric akai na nitrogen a zazzabi daidai 1.000528 zuwa 25 ° C.

Ko, misali, da jiki Properties na lemar sararin samaniya ne halin da irin sigogi. Lemar sararin samaniya - shi ne ma wani colorless iskar gas da wani takamaiman wari da kuma dandano, shi ya zama duhu-blue tint, da kuma m zama baki a cikin ruwa a jihar. lemar sararin samaniya narkewa zafin jiki ne -192,7 darajõji, kuma tana tafasa a -111,9 ° C. Lemar sararin samaniya ne mai narkewa a cikin ruwa, yana da wani dielectric akai na 1.0019 (a 0 ° C), da kuma na da yawa na 0,002144 g / cm3 (at 20 ° C).
