The correct answer is A
Step-by-step explanation:
A Venn diagram is a type of visual tool used to describe the commonalities, and differences of two or more aspects of a broader topic or issue. In the case of the Venn diagram presented, this explains the properties of matter by classifying properties into physical properties and chemical properties. This implies physical properties should be classified in circle A, chemical properties in circle C, and common properties in space B.
According to this, the freezing point should be placed in A, because this is part of the physical properties of matter as the freezing point can be observed, and tested or measure without changing the substance in the same way that viscosity, density or boiling point. Also, chemical properties such as pH or flammability require chemical processes that change the composition of the substance, and the freezing point only changes the state of a substance from liquid to solid.
