What information is provided in the physical properties section of the MSDS?

The physical properties section of the Material Safety Data Sheet (MSDS) primarily offers critical information regarding the characteristics of a chemical substance, such as its boiling point, melting point, and freezing point. These properties help in understanding how the substance behaves under varying temperature conditions, which is vital for safe handling and storage.

For instance, knowing the boiling point aids in determining the temperatures at which a chemical transitions from liquid to vapor, which is essential for controlling evaporation hazards. Understanding the melting point and freezing point is equally important for logistics, as these properties dictate the phases a substance will be in at different temperatures and can guide proper storage practices to prevent accidents or spills.

While the other options pertain to relevant safety considerations, they do not typically fall under the physical properties section of the MSDS. Therefore, boiling, melting, and freezing points are specifically what this section addresses, making it the correct focus for this inquiry.
