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