This is because the intermolecular spaces between molecules of the solvent reduce and less solute can be accommodated. When a saturated solution begins to cool, the solute begins to precipitate. This is because raising the temperature increases intermolecular spaces between molecules of the solvent whereby more solute molecules can occupy. It may be able to dissolve more when the temperature is raised. When a solution is saturated, it means it cannot dissolve more solute at that given temperature. This, therefore, means the solute can not begin to form crystals in the solution which only occurs in saturated solutions. NO, a solute cannot crystallize from an unsaturated solution without changing the solution temperature.Īn unsaturated solution means it can dissolve more solute.
There are a few abilities that most scientists must possess in order to succeed, even if certain skills needed by scientists will vary based on the business they work in. Using this process, one may gather quantifiable evidence to support a theory. The scientific method is the approach that is most frequently utilized in science. With the use of numerous analytical and testing techniques, scientists seek to discover quantifiable facts. There are many different kinds of scientists, and almost every sector of the economy needs the expertise and research that these experts provide. Scientists may develop hypotheses, test them using a variety of tools, including data and statistics, and then draw conclusions based on the results. So the correct option is D.Īn expert who conducts and gathers research to further knowledge in a particular field is referred to as a scientist. The scientist provides unbiased information to the government.
