Ubudlelwane phakathi kokuqhuba kobushushu bezinto zokwambathisa yi-λ=k/(ρ×c), apho u-k emele ukuqhuba kobushushu bezinto, u-ρ emele uxinano, kwaye u-c emele ubushushu obuthile.
1. Ingcamango yokuqhuba ubushushu
Kwizinto zokwambathisa, ukuhanjiswa kobushushu kubhekisa kubuchule bobushushu kwindawo nganye kwiyunithi yezinto ukuba zidlule kwizinto ngexesha ngalinye, oko kukuthi, izinga lokudluliselwa kobushushu. Ngokuqhelekileyo kubonakaliswa kukuhamba kobushushu kwindawo nganye kwiyunithi ngexesha ngalinye xa umahluko wobushushu uyi-1K, kwaye iyunithi yi-W/(m·K). Ubukhulu bokuhanjiswa kobushushu buxhomekeke kukuhanjiswa kobushushu kunye nomahluko wobushushu bezinto.
2. Ifomula yokubala yokuqhuba ubushushu
Ukuqhuba kobushushu bezinto zokwambathisa kunxulumene noxinano, ubushushu obuthile kunye nokuqhuba kobushushu bezinto, kwaye ubudlelwane phakathi kwazo buyi: λ=k/(ρ×c).
Phakathi kwazo, u-k umele ukuhanjiswa kobushushu bezinto, iyunithi yi-W/(m·K); u-ρ umele uxinano, iyunithi yi-kg/m³; u-c umele ubushushu obuthile, iyunithi yi-J/(kg·K). Le fomula isixelela ukuba ukuba sifuna ukunciphisa ukuhanjiswa kobushushu bezinto zokwambathisa, kufuneka sinciphise uxinano, amandla athile obushushu kunye nokuhanjiswa kobushushu bezinto.
3. Izinto ezichaphazela ukuqhuba kobushushu
Ukuqhuba kobushushu bezinto zokwambathisa kuchaphazeleka zizinto ezininzi, ezinje ngobushushu, iipropati zesakhiwo sezinto (ezinje ngesakhiwo sekristale), ukwakheka kweekhemikhali zezinto, ukusebenzisana kwezinto, njl. Ukongeza, uxinano, umxholo wamanzi, ukuxinana kunye nezinye iiparameter zezinto zokwambathisa ziya kuchaphazela ukuqhuba kobushushu.
