Example Questions
Example Question #1 : Describe Properties Of Substances
The property of metal that means it is easily bent or hammered into different shapes is:
conductivity
malleability
flammability
electromagnetic
malleability
The answer is "malleability." This is a property of metals which means they are easily bent or hammered into new shapes.
Example Question #2 : Describe Properties Of Substances
Mass, volume, ductility, boiling point, melting point, and density are all examples of:
chemical and physical properties
chemical properties
physical properties
physical properties
The answer is "physical properties" because all of these properties are observable in physical changes.
Example Question #3 : Describe Properties Of Substances
Which property of a substance means that electricity and heat can easily pass thorough it?
malleability
density
conductivity
flammability
conductivity
The answer is conductivity. Conductivity means electricity and heat can easily pass thorough a substance.
Example Question #4 : Describe Properties Of Substances
Which answer choice is NOT likely to be a property of a metal?
not very reactive
highly flammable
malleable
naturally occurs as a solid
highly flammable
The answer is highly flammable. Most metals are not easily caught on fire.
Example Question #5 : Describe Properties Of Substances
Density is the property of a substance that means:
how much space a substance takes up
the amount of matter per unit volume of a substance
how easy it is to set it on fire
how easy it is to bend into different shapes
the amount of matter per unit volume of a substance
Density is the property of a substance that describes the amount of matter per unit volume of a substance.
Example Question #6 : Describe Properties Of Substances
Which answer choice is NOT an example of a physical property of a substance?
luster
corrosiveness
ductility
melting point
corrosiveness
The answer is corrosiveness because corrosion occurs through chemical reactions and is therefore a chemical property
Example Question #7 : Describe Properties Of Substances
Which answer choice is NOT a chemical property of a substance?
boiling point
flammability
toxicity
reactivity
boiling point
The answer is boiling point because when a substance boils and changes states, it is undergoing a physical change. Therefore boiling point is a physical property.
Example Question #8 : Describe Properties Of Substances
What is a property of a substance?
a characteristic that can be deserved
a characteristic that can be observed in a chemical change
none of these
a characteristic that can be observed in a physical change
a characteristic that can be deserved
The answer is "a characteristic that can be observed" because whether a property is chemical or physical is a sub-classification of a property.
Example Question #9 : Describe Properties Of Substances
Combustibility, toxicity, PH, reactivity, ability to rust, and flammability are all examples of:
chemical properties
none of these
physical properties
both chemical and physical properties
chemical properties
The answer is "chemical properties" because they are all observable in chemical changes.
Example Question #10 : Describe Properties Of Substances
Malleability, flammability, melting point, boiling point, and toxicity are all examples of:
chemical properties
physical properties
both physical and chemical properties
none of these
both physical and chemical properties
The answer is "both chemical and physical properties" because they can be observed in physical and chemical changes.
