Deatach
'S e stuth a tha na ghas aig teòthachd nas ìsle na a theòthachd riatanach a th' ann an deatach.[1] Le sin, co-dhlùthaichidh an t-uisge a tha na ghas gu uisge lionnna/soladach ma thèid ìre a' bhrùthaidh a tha a' toirt buaidh airsan suas gun an teòthachd aige a dhol sìos aig an aon àm. Air an dàrna làimh, ma cho-dhlùthaicheas gas air choireigin aig teòthachd chunbhalach, thèid am brùthadh suas. Air an làimh eile feumar an teòthachd a lughdachadh airson stuth nach eile na dheatach gu stuth lionna. Mar eisimpleir, 's ann aig 374 °C a ruigeas an t-uisge a theòthachd riatanach agus chan fhaod uisge lionna a dhol nas àirde na sin. Faodaidh stuth a tha na dheatach a bhith ann còmhla ri stuth lionna/soladach aig an aon àm. Ma ghabh sin a thachair, bidh cothrom ann agus bidh brùthadh a' ghas co-ionnan ri na tha a' toirt buaidh air an stuth lionna/soladach.[2]
Canar deatach ri stàit a' ghas (stàit far nach bi na moileciuilean a' frith-ghluasad ri ceanglaichean a dhèanamh eatorra fhèin, seach gan ais-bualadh, agus a' toirt cruth agus volum del recipient far a bheil iad, gan tuiteam a-mach à chèile, is iad a' sìor-leudachadh) aig an teòthachd riatanach. Chitheamaid san dealbh, 's e an ìre ghasach a chnar ris an deatach a tha dùinte leis an loidhne bheartagail a sheallas an teòthachd riatanach agus na lùban gorma (an lùb deatachaidh) lei san lùb uile-dheatachaidh annn an dearg, a sheallas ciamar a dh'atharraicheas stuth lionna/soldach gu bhith na dheatach. 'S e an gas a tha air a theasachadh cus agus e nas teotha na an teòthachd riatanach aige ach fon bhrùthach riatanach aige.
Na rachamaid ann am breisleach: 's ann eadar-dhealaichte 's a tha deatach agus gas.[3] Mar as àbhaist, cha chanar deatach ach ri deatach an uisge, leis gur e sin an gas a chruthaichear ma ghoilear an t-uisge gu 100 ° C ann an àile fo bhrùthadh àbhaisteach, air neo nuair a dh' atharraichear stàie an uisge, is an t-uisge aig teòthachd sam bi a tha fon teòthachd riatanach, agus am brùthadh fo ìre brùthadh an uisge aig an teòthachd sin. 'S e dèabhadh a chanar ri sin.
