Ngati mlingo wa mphamvu za reactants ndi apamwamba kuposa mlingo mphamvu za mankhwala ndi anachita ndi exothermic (mphamvu zatulutsidwa panthawi ya anachita). Ngati mlingo wa mphamvu za mankhwala ndi apamwamba kuposa mlingo mphamvu za reactants ndi endothermic reaction.

Mwachidule, ndi ziti mwa zomwe zimachititsa kuti zikhale zovuta kwambiri?

An exothermic anachita ndi mankhwala anachita momwe mphamvu zochepa zimafunikira kuti zithetse mgwirizano mu reactants kuposa momwe zimatulutsidwa pamene zomangira zatsopano zimapanga muzinthu. Pa nthawi ya exothermic anachita, mphamvu imaperekedwa nthawi zonse, nthawi zambiri ngati kutentha. Kuyaka konse zochita ndi exothermic zimachitikira.

Komanso, chitsanzo cha endothermic ndi chiyani? Izi zitsanzo zitha kulembedwa ngati ma chemical reactions, koma zimaganiziridwa kuti ndizo endothermic kapena njira zotengera kutentha: Kusungunula madzi oundana. Kusungunula mchere wolimba. Kutuluka madzi amadzimadzi. Kutembenuza chisanu kukhala nthunzi wamadzi (kusungunuka, kuwira, ndi kutuluka, kawirikawiri, ndizo endothermic njira.

Pambuyo pake, wina angafunsenso, Kodi Madzi Owiritsa ndi owopsa kapena ndi owopsa?

Tonse tingayamikire zimenezo madzi sizingochitika zokha wiritsani kutentha kwa chipinda; m’malo mwake tiyenera kuutenthetsa. Chifukwa tiyenera kuwonjezera kutentha, madzi otentha ndi njira yomwe akatswiri amatcha endothermic. Mwachionekere, ngati njira zina zimafuna kutentha, zina ziyenera kutulutsa kutentha zikachitika. Izi zimatchedwa exothermic.

Kodi equation ya endothermic reaction ndi chiyani?

General equation ya endothermic reaction ndi: Zochita + Mphamvu → Zogulitsa. Mu endothermic reactions, kutentha kwa zinthu kumakhala kotsika kuposa kutentha kwa amayankha.
