Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Kupfuura: Titania inofungidzirwa kuva yakaumbwa kubva muaccretion disc kana subnebula; disc yegasi neguruva iro rakanga riripo rakakomberedza Uranus kwenguva yakati pashure pokuumbwa kwaro kana kuti rakasikwa nokurova kukuru uko sezvingabvira zvikuru kwakapa Uranus kukombama kwakakura. Kuumbwa chaiko kweiyo subnebula hakuzivikanwi; zvisinei, kuwanda kwakanyanya kweTitania nedzimwe mwedzi yeUranus zvichienzaniswa nemwedzi yeSaturn kunoratidza kuti ingangove yaive isina mvura. Nhamba huru dze nitrogen nekabhoni dzingave dziripo muchimiro che carbon monoxide ne N2 panzvimbo pe ammonia nemethane. Mwedzi yakaumbwa mu subnebula yakadaro yaizova nemvura yakaita chando shoma (ine CO neN2 yakabatwa se clathrate) uye dombo rakawanda, zvichitsanangura kuwanda kwazvo. Kuwedzera kwaTitanian zvimwe kwakatora zviuru zvemakore. Zvinhu zvacho zvaipindirana nokuwanda kwemvura zvakaita kuti nzvimbo yokunze yemwedzi ipise. Tembiricha yakakwira yeinenge 250 K (−23 °C) yakasvika pakadzika kwemakiromita makumi matanhatu. Pashure pokuguma kwokuumbwa, rukoko rwomukati rwakadzikama, nepo mukati maTitanian makadziya nemhaka yokuora kwezvinhu zvine mwaranzi zviripo mumatombo aro. Mvura inotonhorera iri pedyo nepasi yakaderera, nepo iri mukati yakakura. Izvi zvakakonzera kuti goko romwedzi riomerwe zvokuti rakatanga kutsemuka. Mamwe emakoronga aripo nhasi angave ari mugumisiro waikoku. Nzira yacho yakatora makore anenge mamiriyoni 200, zvichireva kuti basa ripi neripi romukati rakaguma mabhiriyoni emakore akapfuura. Kupisa kwokutanga kwokuwedzera pamwe chete nokuora kunopfuurira kwezvinhu zvine mwaranzi zvichida kwakanga kwakasimba zvakakwana kunyungudutsa chando kana chimwe chinhu chinopesana nechando chakadai seammonia (muchimiro cheammonia hydrate) kana munyu waivapo. Kuenderera mberi kwekunyunguduka kungave kwakatungamirira kukuparadzaniswa kweaizi nematombo uye kuumbwa kwechinhu chine matombo chakakomberedzwa nomucheka wechando. Nzvimbo yemvura yakasviba (gungwa) ine ammonia yakanyunguduka ingangodaro yakaumbwa pamuganhu wedenga. Tembiricha ye eutectic yemusanganiswa uyu ndeye 176 K (−97 °C). Kana tembiricha ikaderera pasi peiri kukosha, gungwa raiz...  Mubvunzo: Gungwa raizova rakadini kudai tembiricha yaro yakaderera kupfuura 176 K?
