M2.2 Nature and properties of solids and fluids

What is the role of bonds between particles in materials?

• They determine the material's weight

• They influence the material's properties

• They change the material's color

• They affect the material's taste

What is the tendency of a material to resist indentation called?

• Flexibility

• Hardness

• Transparency

• Conductivity

What is the tendency to withstand an applied load without failure or plastic deformation?

• Toughness

• Strength

• Brittleness

• Flexibility

Which of the following is an example of a material with high strength?

• Rubber

• Wood

• Steel

• Glass

Which of the following materials is considered brittle?

• Rubber

• Concrete

• Metal coil spring

• Hard steel

What is the elastic limit?

• The point at which a material breaks

• The maximum stress a material can withstand without permanent deformation

• The temperature at which a material melts

• The force required to change a material's shape

What is the main difference between elasticity and plasticity?

• Elasticity involves permanent deformation, plasticity does not

• Elasticity is the tendency to remain in a new shape, plasticity is not

• Elasticity returns to original shape, plasticity remains in new shape

• Elasticity requires more force to change shape, plasticity requires less

What is a volatile liquid?

• A liquid that freezes at normal temperature

• A liquid that readily evaporates at normal temperature

• A liquid that solidifies quickly

• A liquid that does not evaporate

Which of the following is an example of a volatile liquid?

• Water

• Petrol

• Olive oil

• Vinegar

Which of the following is NOT a volatile liquid?

• Methylated spirits

• Ethanol

• Water

• Petrol
