Mocheso o khethehileng, mocheso o utloahalang, le mocheso o patiloeng ke bongata ba 'mele:
The mocheso o itseng ntho ke bongata ba mocheso o tlamehang ho fuoa boima ba yuniti ea ntho eo ho phahamisa mocheso oa eona ka yuniti e le 'ngoe. Chelete eo e fapana haholo ho latela mocheso oo ntho eo e leng ho eona pele mocheso o sebelisoa ho eona. Mohlala, ho nka khalori e le 'ngoe ho eketsa metsi ka mocheso oa kamore ka degree e le ngoe, empa ho nka feela khalori ea 0.5 ho eketsa mocheso oa leqhoa ho -5 likhato ka degree e le' ngoe. Mocheso o khethehileng o boetse o latela khatello ea sepakapaka. Ntho e ts'oanang le khatello e tlase ea sepakapaka e na le mocheso o tlase o tlase. Mehlala e ka tlase e nepahetse bakeng sa mocheso oa likhato tse 25 le khatello ea sepakapaka se le seng.
The mocheso o utloahalang Ke mocheso oo 'mele o ka o fumanang ntle le ho ama sebopeho sa limolek'hule. Haeba sebopeho sa limolek'hule se sa fetohe, mmuso (o tiileng, o metsi, o nang le moea o mongata) ha o fetohe. Kaha sebopeho sa limolek'hule ha se fetohe, phetoho ea mocheso ea bonoa, ke ka hona e bitsoang mocheso o nang le kelello.
The mocheso o morao Ke matla (mocheso) a hlokahalang hore ntho e fetole karolo (boemo). Haeba phetoho e tloha ho tiileng ho isa ho metsi e bitsoa mocheso oa fusion. Haeba phetoho e tsoa ho mokelikeli ho ea ho khase e bitsoa mocheso oa vaporization. Ha mocheso o sebelisoa nthong e fihletseng mocheso moo o fetohang boemo, ho ke ke ha khoneha hore mocheso o eketsehe, o mpa o fetoha boemo. Mohlala, haeba mocheso o ntse o sebelisoa ho metsi a belang, o ke ke oa feta 100 ° C. Ho ipapisitse le ntho eo, mocheso o sa tsoa tloaela o ka lekanyetsoa ka likhalori ka grama kapa ka kilojoule ka kilogram (KJ).
