Term
|
Definition
| D= M/V (unit = g/ml or g/cm³) |
|
|
Term
| How do you change the density of an object? |
|
Definition
By changing temperature or pressure
Temp(up) -> Volume(up) -> Mass stays the same -> Density(down)
Temp(d) -> Volume (d) -> Mass stays the same -> Density (up)
Pressure(Up) ->Volume (d) -> Mass stays the same -> Density(up)
Pressure(d) ->Volume (up) -> Mass stays the same -> Density(d) |

Nature of change?
what is change? |
|
Definition
Change can be described as the occurrence of an event.
If change has many variables it will be more difficult to predict change |
|
|
Term
|
Definition
| Occurs when the properties of a system are altered |
|
|
Term
| What happen if the nature of change is known...? |
|
Definition
| then the rate and direction of change can be predicted. |
|
|
Term
| predictions will be more accurate... |

Term
| Relationship between Energy & Change |
|
Definition
- All change involves the transfer of Energy
- If energy is lost in one part of a system then it must be gained at another part of the system and change will occur
- The exchange of energy occurs at an interface |
|
|
Term
|
Definition
| Interface is the point where the energy is exchanged |
