What are the products formed when a marshmallow undergoes combustion?

Carbon dioxide, water vapor, light, and heat

How is corn syrup produced?

Through chemical and enzymatic reactions

By extracting directly from corn

What is the purpose of using synthetic materials in marshmallows?

To achieve specific properties like melting behavior, sweetness, and texture

What does the passage imply about the nature of marshmallows?

They are a manufactured product resulting from human-designed processes

They are made only from raw ingredients

Why does a marshmallow seem to disappear when it burns?

The solid sugars are converted into gases and escape into the air

The marshmallow melts completely

The marshmallow is absorbed by the flames

What would happen to the mass if you could trap all the products of a burned marshmallow and weigh them?

The mass would be the same as the original

The mass would be less than the original

The mass would be more than the original

How do endothermic and exothermic reactions demonstrate energy movement in chemical systems?

By showing energy absorption and release

What does the law of conservation of energy state?

Energy cannot be created or destroyed, only changes form.

Energy can be created and destroyed.

Energy is always lost during transformation.

Energy is only created during combustion.

What happens to the chemical energy in sugar when a marshmallow is roasted?

It is converted into thermal and light energy.

Why do you feel warmth near a burning marshmallow?

Because energy is flowing and transforming.

Because the marshmallow is losing energy.

Because the energy is being destroyed.

Because the marshmallow is absorbing energy.

What scientific principles can be learned from roasting marshmallows?

Molecular transformations and energy conversion

Photosynthesis and cellular respiration

How does roasting marshmallows demonstrate the conservation of energy and matter?

By showing how energy is absorbed and released during the roasting process

By illustrating the process of photosynthesis

By demonstrating the principles of gravity

By explaining the theory of relativity

In what way does roasting marshmallows help us understand synthetic materials?

By observing the behavior of marshmallows as they heat and change form
