This study researched 122 high school students’ and 97 chemistry majored teachers’ perceptions on evap-oration and boiling compared heating and no heating situations. From the results, it was found that the teachers’ thoughtsof evaporation and boiling depend on the situation were stable, but students’ thoughts were depend on the situations. Thehigh school students thought evaporation as boiling on the situation of heating and thought boiling as evaporation on thesituation of no heating. These phenomena were related to the explanations of science textbooks. In many textbooks, evap-oration concept was explained in the situation of no heating and boiling concept was explained in the situation of heating.Keywords: High School Student, Teacher of Chemistry Major, Misconception, Scientific Conception, Evaporation,Boiling, Situation Dependent . . ,  .
