An engineer investigates the thermal properties of a titanium alloy specimen. The engineer measures the temperature of the specimen every minute while it is heated within a vacuum chamber at a constant power input.
Figure 1 shows a graph of the results.
| Time (minutes) | Temperature (°C) |
|---|---|
| 0 | 135.0 |
| 1 | 147.5 |
| 2 | 160.0 |
| 3 | 172.5 |
| 4 | 185.0 |
| 5 | 197.5 |
Predict the temperature of the titanium alloy specimen if the heating is continued up to 12 minutes.
