Question How do water fire extinguishers work? A. By removing the heat from the fire B. By smothering the fire C. By creating a barrier C

Answer 1

A. By removing the heat from the fire.

Answer 2

## Step 1: Understanding the Fire Triangle The fire triangle is a model for understanding the necessary ingredients for most fires. It includes three elements: heat, fuel, and oxygen. For a fire to start and continue burning, all three elements must be present. ## Step 2: Understanding the Role of Water Fire Extinguishers Water fire extinguishers work by removing one of the elements of the fire triangle. Specifically, they remove the heat from the fire. Water has a high heat capacity, meaning it can absorb a lot of heat. When water from the extinguisher comes into contact with fire, it absorbs the heat, reducing the temperature of the fire. This can stop the combustion process and extinguish the fire. ## Step 3: Evaluating the Options A. By removing the heat from the fire - This is correct, as explained in step 2. B. By smothering the fire - This is typically how foam or CO2 extinguishers work, not water extinguishers. They remove the oxygen element from the fire triangle. C. By creating a barrier - This is also not how water extinguishers work. Some extinguishers create a barrier of foam or other material to separate the fire from its fuel source, but water extinguishers primarily work by cooling the fire. ### The formula for the fire triangle is: \(\text{Fire} = \text{Heat} + \text{Fuel} + \text{Oxygen}\)
