However, they did not always consider that objects in the same surroundings have the same temperature, when they were given new situations, as reported by Tiberghien (1985), Thomaz et al. (2003) and Clark and Jorde (2004). These research studies discussed that confusion is reinforced by the contrast between the cold sensation generated by touching a good conductor such as metal e.g. a pan and the warm sensation by touching an insulator. In contrast with Libyan context, many Libyan students held the alternative conceptions of thermal equilibrium which caused by the hot sensation generated by touching a good conductor and the warm sensation by touching an insulator in the hot day. By these results, it is indicated that the students have learned by memorizing the concept without the fundamental understanding and they faced problem with transferring thermal equilibrium concept because their personal experiences were resisted by the scientific concepts.
