Matter exhibits distinct measurable characteristics that determine how it behaves under mechanical forces, thermal energy, and phase equilibria. Match each physical property of matter on the left with its corresponding scientific description on the right.
- HardnessThe resistance of a solid substance to surface scratching, localized plastic deformation, or mechanical abrasion.
- Specific Heat CapacityThe quantity of thermal energy required to raise the temperature of one unit mass of a substance by one degree Celsius.
- ElasticityThe capacity of a deformed solid material to return to its original shape and size once applied deforming forces are removed.
- Vapor PressureThe force per unit area exerted by an evaporated gas in thermodynamic equilibrium with its condensed liquid or solid phase at a given temperature.
Answer
Hardness matches with the resistance of a solid substance to surface scratching, localized plastic deformation, or mechanical abrasion; Specific Heat Capacity matches with the quantity of thermal energy required to raise the temperature of one unit mass of a substance by one degree Celsius; Elasticity matches with the capacity of a deformed solid material to return to its original shape and size once applied deforming forces are removed; Vapor Pressure matches with the force per unit area exerted by an evaporated gas in thermodynamic equilibrium with its condensed liquid or solid phase at a given temperature.
Each physical property is correctly paired with its foundational scientific definition: Hardness pertains to surface scratch resistance, Specific Heat Capacity defines the heat required to change temperature per unit mass, Elasticity governs reversible mechanical deformation, and Vapor Pressure quantifies phase equilibrium pressure in a closed container.
