17
Q

What is a physical property?:

A

Physical property – quality or condition of a substance that describes the matter. It can be observed or measured without changing the composition of that substance

18
Q

What are six physical properties?:

A
  • Odor
  • Colour
  • Density
  • Solubility
  • Melting point
  • Boiling point
19
Q

What are four physical properties referring to metals?:

A
  • Conductivity

  • Ductility
  • Luster
20
Q

Physical properties used to describe matter can be classified as ______ or _______:

A

Extensive or Intensive

21
Q

Define intensive properties:

A

Intensive properties – depends on the type of matter present, not the amount

22
Q

Give nine examples of an intensive property:

A
  • Density
  • Malleability
  • Conductivity
  • Ductility
  • Luster
  • Melting point
  • Boiling point
  • Colour
  • Temperature
23
Q

Define extensive properties:

A

Extensive properties – depends on the amount of matter in a sample

24
Q

Give five examples of an extensive property:

A
  • Mass
  • Length
  • Volume
  • Shape
  • Size
25
Q

Most properties are ________:

A

Intensive

26
Q

Give the definition for a chemical property:

A

Chemical property – the ability of a substance to undergo a change in composition

27
Q

T/F – A chemical property can only be observed by changing the substance:

A

True

28
Q

Give seven examples of a chemical change:

A
  • Rust
  • Burn
  • Rot
  • Decompose
  • Ferment
  • Explode
  • Corrode
29
Q

Give a definition for physical change:

A

Physical change – some properties of the substance change, but the composition does not change (still the same substance)

30
Q

Give eight examples of a physical change:

A
  • Boil
  • Freeze
  • Melt
  • Condense
  • Break
  • Split
  • Cut
  • Grind
31
Q

Give a definition for chemical change:

A

A change in the properties of a substance producing a different composition and a new substance

32
Q

What is a chemical reaction?:

A

Chemical reaction – one or more substances turn into one or more new substances

33
Q

T/F – Mass is always conserved during a chemical reaction (Law of Conservation of Mass):

A

True

34
Q

What is a reactant?:

A

Reactant – substance present at the beginning (of a chemical reaction)

35
Q

What is a product?:

A

Product – substance present at the end (of a chemical reaction)

36
Q

List five pieces of evidence suggesting a chemical change:

A
  • Evolution of a gas
  • Formation of a precipitate (ppt)
  • Colour change
  • Evolution of heat
  • Odor produced
