A technician tests a burner using a carbon-containing fuel. The mass of solid particles collected each minute is measured at different air flow rates.
| Air flow rate (L/min) | Mass of solid particles collected (mg/min) |
|---|---|
| 8 | 36 |
| 12 | 21 |
| 16 | 9 |
Describe the relationship between the air flow rate and the mass of solid particles collected.
The air flow rate is then increased to 20 L/min.
Explain the trend shown in the table and predict the mass of solid particles collected at 20 L/min compared with the mass collected at 16 L/min.
