  • Why did you bring damp logs?Now,the fire will take longer to burn.
  • I'll explain it to you.
  • Why will the fire take longer to burn if the logs are damp?
  • Now,the logs of wood are damp because the presence of water causes the temperature to drop.
  • Thus,more amount of heat is to be applied in order to increase the temperature of the logs of wood to their ignition temperature so that they can burn and produce fire.
  • Every substance catches fire at a specific temperature.This temperature is called the ignition temperature.
  • How is that related to the damp logs of wood?
  •  Had our logs of wood been drier,they would,comparatively,have had a higher temperature which means that less heat would be required in order to make it reach it's ignition temperature.Because of this,lesser effort is needed and there are less smooth or slow rates of reaction.
  • Great idea!We better hurry up.It's getting quite dark.
  • Wow!I never knew there was so much science behind setting up a camp fire.Let's go and get some dry logs of wood so we can get our fire started.
