Lea e i ai le maualuga maualuga e le mafai ona pa

Fa'avasegaga-fa'asa: O le aofaʻiga sili ona taua o le IIC, e aofia ai talosaga a le IIB ma le IIA; IIB e sili atu i le IIA ile fa'avasegaga.

Maualuluga o luga ole vevela: E faasino lea i le maualuga o le vevela e mafai ona ausia e masini eletise i lalo ole tulaga sili ona leaga, e ono fa'amumuina ai le ea fa'apapa. O le maualuga maualuga o le vevela e tatau ona maualalo nai lo le vevela afi.

O lesi foi mea: I si'osi'omaga o lo'o fa'aogaina ai masini e fa'asa'o pa, pe afai o le vevela vevela o le mea pāpā kasa e 100°C, ona tatau lea ona tumau le maualuga o le vevela o so'o se vaega o le masini i lalo ole 100°C.
