Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Kupfuura: Franklin akacherechedza nheyo yefriji kupfurikidza nokucherechedza kuti pazuva rinopisa zvikuru, iye airamba achitonhorera zvikuru muhembe yakanyorova mumhepo pane zvaaiita mune yakaoma. Kuti anzwisise zvakajeka zvikuru chinoitika ichi Franklin akaita miedzo. Muna 1758 pazuva rinopisa muCambridge, kuEngland, Franklin nomumwe musayendisiti John Hadley vakaedza nokuramba vachinyorovesa bhora rethermometer yemekiyuri neether uye vachishandisa mabhero kuti vaputse ether. Nokutsvaira kumwe nokumwe kwakatevera, thermometer yakarava tembiricha yakaderera, pakupedzisira ichisvika 7 °F (−14 °C). Imwe thermometer yakaratidza kuti tembiricha yomukamuri yaigara iri 18 °C. Mutsamba yake inonzi Cooling by Evaporation, Franklin akati, "Munhu angaona mukana wokutonhora munhu kusvikira afa pazuva rinopisa rezhizha".  Mubvunzo: Mugore ripi musayendisiti John Hadley akaedza kunyorovesa bhora nematheromita emekiyuri?
