Graphing Practice Problem #4
The volume of a gas decreases as the temperature of the gas decreases. A sample of gas was collected at 100 degrees Celsius and then cooled. The changes in the volume of the sample are shown below.
| T ( oC ) | V ( ml ) |
|---|
| 100 | 317 |
|---|
| 80 | 297 |
|---|
| 60 | 288 |
|---|
| 40 | 278 |
|---|
| 30 | 252 |
|---|
| 20 | 243 |
|---|
| 10 | 236 |
|---|
| 0 | 233 |
|---|
| -10 | 227 |
|---|
| -30 | 202 |
|---|
- Graph the data.
- Construct another graph that will allow you to extrapolate (extend the graph beyond measured data) the graph to reach a gas volume of 0 ml. The temperature at which the volume of the gas reaches zero is the theoretical temperature of Absolute Zero. From this graph, what is the Celsius Temperature for Absolute Zero?
