Which of these things would have the lowest ignition temperature?

Options

A. Paper
B. Wood
C. LPG
D. Glass

Answer

To determine which of the given substances has the lowest ignition temperature, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Ignition Temperature**:
- Ignition temperature is defined as the minimum temperature at which a substance starts to burn. This means that if a substance reaches this temperature, it will ignite and continue to burn.

2. **Identify the Substances**:
- The question provides us with several options (though they are not specified in the question). For the sake of this solution, let's consider common substances like LPG (Liquefied Petroleum Gas), paper, wood, and glass.

3. **Research the Ignition Temperatures**:
- We need to know the ignition temperatures of the substances. Generally:
- **LPG**: Approximately 320°C
- **Paper**: Approximately 233°C
- **Wood**: Approximately 300°C
- **Glass**: Very high, typically above 1000°C

4. **Compare the Ignition Temperatures**:
- Now, we compare the ignition temperatures of these substances:
- LPG: 320°C
- Paper: 233°C
- Wood: 300°C
- Glass: >1000°C

5. **Determine the Lowest Ignition Temperature**:
- From the comparison, we can see that paper has the lowest ignition temperature at 233°C, followed by wood at 300°C, then LPG at 320°C, and glass has the highest ignition temperature.

6. **Conclusion**:
- Therefore, the substance with the lowest ignition temperature among the options is **Paper**.

### Final Answer:
The substance with the lowest ignition temperature is **Paper**.
