Intshayelelo

Ukutshintshwa kobushushu ngumbono osisiseko kwifiziksi nakwikhemistri. Iingcamango ezimbini ezibalulekileyo ezinxulumene nokutshintshwa kobushushu bubushushu obuthile kunye nomthamo wobushushu. La magama ahlala esetyenziswa ngokufanayo, kodwa eneneni kukho umahluko omkhulu phakathi kwawo.

Calor específico

Ubushushu obuthile buchazwa njengobungakanani bamandla ayimfuneko ukunyusa ubushushu beyunithi yobunzima bento ngeqondo elinye ngokukaCelsius. Ngokwezibalo, inokuchazwa ngolu hlobo:

C = Q / (m * ΔT)

  • C bubushushu obukhethekileyo
  • Q ngumlinganiselo wobushushu
  • m bubunzima bento
  • ΔT lutshintsho lobushushu

Ubushushu obuthile yipropathi enzulu yento ethile, oko kuthetha ukuba Akuxhomekekanga kubungakanani bento ekhoyo.

Capacidad calorífica

Umthamo wobushushu uchazwa njengobungakanani bamandla ayimfuneko ukunyusa ubushushu bento ngeqondo elinye ngokukaCelsius. Ngokungafaniyo nobushushu obuthile, umthamo wobushushu uxhomekeke kubungakanani bento ekhoyo.

Umxholo okhethekileyo- Cofa Apha  Umahluko phakathi kwesantya kunye nesantya

Umthamo wobushushu unokubonakaliswa ngolu hlobo:

Cp = Q / ΔT

  • I-Cp ngumthamo wobushushu kwixinzelelo rhoqo
  • Q ngumlinganiselo wobushushu
  • ΔT lutshintsho lobushushu

Elinye igama eliyeleleneyo yi-Cv, engumthamo wobushushu kwivolumu engaguqukiyo.

Ukuxhomekeka kubungakanani bento

Ubushushu obuthile buyinto emandla kwaye akuxhomekekanga kubungakanani bento ekhoyo. Kwelinye icala, amandla obushushu yipropati ebanzi kwaye ixhomekeke kubungakanani bento ekhoyo.

Unidades de medida

Ubushushu obuthile bulinganiswa nge-J/(g·°C) ngelixa umthamo wobushushu ulinganiswa nge-J/°C.

Uxinzelelo kunye nomthamo

Umthamo wobushushu unokwahlulwa ube ngumthamo wobushushu kuxinzelelo olungagungqiyo (Cp) kunye nomthamo wobushushu kumthamo ongatshintshiyo (Cv). Ixabiso leCp likhulu kunexabiso leCv.

Izigqibo

Ngelixa omabini la magama enxulumene nokuhanjiswa kobushushu, kubalulekile ukuqaphela ukuba ubushushu obuthile kunye nomthamo wobushushu ziingqikelelo ezahlukeneyo. Umahluko ophambili kukuba ubushushu obuthile buyinto emandla, ngelixa amandla obushushu yipropati ebanzi exhomekeke kubungakanani bezinto ezikhoyo.
