These describe how a material behaves in relation to physical influences.

• A. Toxic Properties
• B. Physical Properties
• C. Physical Properities
• D. Chemical Properties

Answer: (B)

Physical properties describe how a material responds to physical influences such as heat, pressure, or changes in state, without changing its chemical identity. This includes characteristics like melting point, boiling point, density, viscosity, vapor pressure, color, hardness, electrical conductivity, and refractive index. The statement is about how a material behaves under physical influences, so it aligns with physical properties. The other terms shift away from that idea: toxic properties concern health effects, chemical properties describe how a material reacts chemically with other substances, and the misspelled term isn’t a recognized category. In hazmat practice, knowing these physical properties helps predict behavior during storage, transport, and emergency scenarios—what might happen to pressure, phase, or vapor release under changing conditions.
