2. Ignition temperature is the lowest temperature at which a substance that can combust burns in air and continues to burn.

3. Two common types of fire extinguishers: air pressurized water and $CO_{2}$.

4. (Please check this with your teacher, there are different types of combustion and I'm not sure which ones you're studying/which ones are appropriate for your curriculum): Major products of the combustion process: $CO_{2}$ and $H_{2}O$ - for when hydrocarbons burn in excess $O_{2}$.

5. 2 inflammable substances: alcohol and LPG (Liquified Petroleum Gas).
