Chinyorwa pamusoro peKuwanda uye simba regiravhiti
Density
Hunhu hunokosha hwechinhu ichi kuwanda. Kuwanda kwechinhu ndicho chiyero chehukuru nehukuru. Zvakanyorwa nemasvomhu:
ρ = m / V
ρ (rho) ibhii rechiGiriki rinowanzo shandiswa kuratidza density, m ihuremu uye V ivhoriyamu. Density yemvura yakafanana yakasiyana nedensity yechinhu chakasimba chakafanana. Semuenzaniso, simbi ine density yakafanana muchikamu chimwe nechimwe. Mumhepo yePasi, density yayo yakakura kubva pamusoro pePasi, density yayo idiki, nepo mumvura yegungwa, density yemvura yegungwa inowedzerawo. Density yemvura yakafanana inogona kutsamira pazvinhu zvakaita setembiricha nekumanikidzwa.
Chikamu cheInternational System che density ikirogiramu pa cubic meter (kg/m3 ) . Kune ma CGS units, chikamu che mass density chinoratidzwa mumagiramu pa cubic centimeter (gr/cm3 ) . Inotevera ndiyo data re density yezvinhu zvakasiyana-siyana.
Kuwanda kwezvinhu zvakataurwa mutafura iri pamusoro apa ndiko kuwanda kwezvinhu pa 0 o C uye kumanikidzwa kwe 1 atm (mhepo, atm = unit of pressure).
Simba rakakashama
Simba guru remagetsi (specific gravity) ndiro chiyero chehuwandu hwechinhu nehukuru hwemvura. Simba guru remagetsi rechinhu rinogona kuwanikwa nekukamura huwandu ne10.3 kg / m3 (103 kg / m3 = kuwanda kwemvura). Simba regiravhiti rakasiyana harina miganhu.
Kana huwandu hwechinhu hudiki pane huwandu hwemvura, chinhu chinoyangarara. Huremu hwechinhu chinoyangarara hwakaderera pane 1. Kusiyana neizvi, kana huwandu hwechinhu hwakakwira kupfuura huwandu hwemvura, huremu hwechinhu hwakakwira kupfuura 1. Muchiitiko ichi, chinhu chinonyura.
