Chemical And Physical Properties Flashcards
What is a physical property?
A characteristic of a substance that can be observed without changing he substance into another
What are he two types of physical properties?
Extensive: depend on the amount of a substance that you have.
Intensive: don’t depend on how much you have
What are some examples of extensive physical properties?
- volume
- mass
- weight
- size
What are some examples of intensive physical properties
- density
- melting point
- boiling point
What are other examples of physical properties?
- colour. - Viscosity
- hardness. - Shape
- odour. - Solubility
- taste
- state
- texture
- lustre
- flexibility
- heat conductivity
- electrical conductivity
- malleability
- ductility
What are Chemical properties?
A characteristic of a substance that can only be observed by changing it into a different substance
What are some examples of chemical properties?
- ability to burn
- ability to rust
- ability to decompose
- ability to react with other chemicals
- instability
- ability to do acid/base reactions
Why do we need to know the different chemical and physical properties?
So that we can use the right elements for the right things
Eg. Titanium is very strong and doesn’t rust so it is often used in jet engines
