Zorluk: OrtaProperties of Matter

A materials technician is evaluating the fundamental characteristics of several substances used in mechanical systems. Match each material property with its correct scientific definition.

  • DuctilityThe physical ability of a solid material to undergo substantial plastic deformation under tensile stress, such as being drawn into thin wire.
  • ViscosityThe internal resistance of a fluid to flow and gradual deformation by shear stress.
  • FlammabilityThe chemical ability of a substance to ignite and sustain combustion in the presence of an oxidizer.
  • SolubilityThe physical capacity of a solute to dissolve homogeneously in a specified solvent at a given temperature.

Cevap

Ductility matches the ability of a solid to be drawn into wires under tensile stress; Viscosity matches the internal resistance of a fluid to flow; Flammability matches the chemical capacity of a substance to ignite and combust; Solubility matches the capacity of a solute to dissolve in a solvent.
Each property is accurately paired with its distinct physical or chemical behavior: ductility refers to tensile elongation into wire, viscosity measures fluid friction against flow, flammability measures chemical reactivity in combustion, and solubility determines dissolution capacity in a solvent.

Adım Adım Çözüm

1
Identify mechanical physical properties of solids
Ductility represents tensile deformation into wires, distinguishing it from malleability (hammering into sheets).
Tensile stress applied to ductile metals allows elongation without brittle fracture.
2
Identify fluid transport physical properties
Viscosity represents fluid shear resistance and thickness.
Internal intermolecular friction governs how quickly or slowly fluids like motor oil or water flow.
3
Differentiate chemical properties from physical properties
Flammability involves chemical transformation through combustion.
Burning produces new chemical substances (carbon dioxide, water vapor, ash), making flammability a chemical property.
4
Identify mixture and dissolution characteristics
Solubility represents the maximum solute concentration in a solvent without altering chemical identities.
Dissolving is a physical process where solute particles disperse evenly within solvent molecules.
