Fire and Combustion Quiz

Fire Characteristics

• Fire is a chemical reaction that involves the rapid oxidation of a fuel source, typically releasing heat, light, and various products of combustion.
• Flames are primarily composed of hot, glowing gases, including water vapor, carbon dioxide, and nitrogen.

High-Temperature Fires

• If a fire is hot enough, it can melt metals, produce toxic fumes, and even create its own weather patterns.

Effects of Fire

• Positive effects of fire include: promoting ecosystem regeneration, creating habitat diversity, and removing hazardous fuels.
• Negative effects of fire include: causing loss of life, destroying property, and releasing greenhouse gases.

Combustion Products

• Oxygen, carbon dioxide, water vapor, and heat are all products of combustion.
• Smoke is NOT a product of combustion.

Fire Appearance

• The visible portion of the fire is called the flame.

Fire Consequences

• Fire can potentially result in loss of life, property damage, and environmental degradation.

Ecological Role of Fire

• Fire plays a crucial role in ecological systems, as it helps to maintain ecosystem balance and promotes biodiversity.

Negative Effects of Fire

• A potential negative effect of fire is the release of hazardous air pollutants, which can harm human health and the environment.
