¿Qué es la combustión?

The video explains combustion as a chemical reaction requiring fuel, oxygen, and heat. It describes how wildfires use trees as fuel and the role of exothermic reactions in releasing energy. Firefighting techniques involve removing heat or fuel to stop fires. Despite destruction, forests recover as sunlight reaches the ground, allowing new growth.

What are the three essential components required for combustion to occur?

• Fuel, water, and heat

• Fuel, oxygen, and heat

• Oxygen, water, and light

• Fuel, light, and water

Which type of reaction is responsible for the energy release during combustion?

• Exothermic reaction

• Endothermic reaction

• Catalytic reaction

• Neutral reaction

How can firefighters stop a fire from spreading?

• By increasing the heat

• By removing heat or fuel

• By removing oxygen

• By adding more fuel

What happens to the environment after a fire has consumed the trees?

• The air becomes permanently polluted

• The soil becomes infertile

• The area becomes barren forever

• New substances are produced, and the forest can recover

What is one of the new substances produced during a fire?

• Plastic

• Metal

• Ash

• Water
