Use the change of state interactive to answer the question. Which of the statements describe limitations or safety concerns of this interactive? The interactive assumes substances change phase as temperature changes. The interactive assumes that the temperature of a solid can be easily measured using a temperature probe. Boiling points must be carefully determined for liquids that are flammable, such as benzene. The interactive assumes that the reaction is a closed system.

Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.
