There are three variables: Mass, Temperature, Density, Volume
Draw 3 kinds of graphs: Mass VS Volume
Temp VS Density
Volume VS Temp
First, list the statistics:
Example:
| TEMP | VOLUME |
| 273 | 152 |
| 320 | 175 |
| 365 | 203 |
| 412 | 226 |
| 455 | 249 |
| 521 | 273 |
| 546 | 302 |
| 580 | 323 |
| 632 | 351 |
Draw the graphs by the graphing tools in Excel:
Solve the slope:
| Slope | 0.554318 |
Lets see a teaching video about how to use Excel Graphing tool:
