#1
Which of the following is a physical property of matter?
Density
ExplanationDensity is a physical property that relates to the mass and volume of a substance.
#2
What physical property of matter does buoyancy depend on?
Density
ExplanationBuoyancy depends on density, as less dense objects float in more dense fluids.
#3
Which physical property determines the ability of a material to conduct electricity?
Electrical resistivity
ExplanationElectrical resistivity is the property determining a material's ability to resist the flow of electric current.
#4
What is the physical property that defines a material's resistance to flow?
Viscosity
ExplanationViscosity is the measure of a material's resistance to flow or deformation.
#5
What physical property determines the degree to which a material can be stretched without breaking?
Elasticity
ExplanationElasticity is the property determining a material's ability to deform and return to its original shape.
#6
Which physical property describes a material's ability to conduct heat?
Thermal conductivity
ExplanationThermal conductivity is the property determining a material's ability to conduct heat.
#7
Which physical property describes a material's ability to absorb light?
Opacity
ExplanationOpacity is the physical property describing a material's ability to absorb light.
#8
What physical property determines the ease with which a material can be deformed under stress?
Plasticity
ExplanationPlasticity is the property determining how easily a material can be deformed under stress.
#9
Which physical property is used to characterize the ability of a material to resist scratching or abrasion?
Hardness
ExplanationHardness is the property characterizing a material's resistance to scratching or abrasion.
#10
What physical property describes the ratio of the density of a substance to the density of a reference substance?
Specific gravity
ExplanationSpecific gravity is the ratio of a substance's density to the density of a reference substance.
