The boiling point of the calcium chloride CaCl2 solution will be higher than that of the boiling point of the sodium chloride NaCl solution, because more molecules are present in the CaCl2 solution since CaCl2 dissociates into three ions while NaCl only dissociates into two ions.
In science, a model is a representation of an idea, an object or even a process or a system that is used to describe and explain phenomena that cannot be experienced directly. Models are central to what scientists do, both in their research as well as when communicating their explanations.
Models have a variety of uses – from providing a way of explaining complex data to presenting as a hypothesis. There may be more than one model proposed by scientists to explain or predict what might happen in particular circumstances. Often scientists will argue about the ‘rightness’ of their model, and in the process, the model will evolve or be rejected. Consequently, models are central to the process of knowledge-building in science and demonstrate how science knowledge is tentative.
Pretty sure its 1 but I may not be correct.
