The video discusses how chemical reactions can occur at different rates, either rapidly like a wildfire or slowly over time. It uses the example of a rusting car to illustrate a slow reaction where iron reacts with oxygen, releasing heat over months or years.

How can energy be released during a reaction?

• Only quickly, like a wildfire

• Only slowly, over years

• Either quickly or slowly

• Neither quickly nor slowly

What happens when iron in a car rusts?

• It releases light energy

• It remains unchanged

• It releases heat as it reacts with oxygen

• It absorbs heat from the air

What is the nature of the heat released during rusting?

• High and intense

• Moderate and quick

• Low and prolonged

• Non-existent

Over what time frame does rusting typically occur?

• Minutes

• Days

• Seconds

• Months or years

Which of the following best describes the reaction of rusting?

• An immediate absorption of heat

• A quick release of energy

• A sudden burst of light

• A slow and steady release of low heat
