Dry Ice and Gas Behavior

The video tutorial demonstrates the sublimation of dry ice, which is solid carbon dioxide, into gas using hot water. This process is shown through a balloon experiment where the gas expands the balloon until it bursts. The tutorial highlights the properties of gases and the concept of sublimation, providing a visual and auditory experience of the transformation from solid to gas.

What is dry ice primarily composed of?

• Compressed air

• Frozen nitrogen

• Solid carbon dioxide

• Water in solid form

What is the process called when dry ice changes directly from a solid to a gas?

• Evaporation

• Condensation

• Sublimation

• Freezing

How is energy added to dry ice in the demonstration?

• By applying pressure

• Using hot water

• Through sunlight

• With a heating pad

What happens to the volume of dry ice when it turns into a gas?

• It decreases

• It remains the same

• It increases

• It disappears

What is the main reason gases take up more space than solids?

• Gases are more elastic

• Gases have less density

• Gases have more energy

• Gases are heavier

Why does the balloon eventually burst in the demonstration?

• The balloon is punctured

• The gas expands beyond the balloon's capacity

• The gas inside cools down

• The balloon material weakens

What safety precaution is mentioned during the demonstration?

• Wear gloves

• Avoid direct sunlight

• Be careful with hot drinks

• Use ear protection

What is the final outcome of the balloon in the demonstration?

• It deflates slowly

• It remains intact

• It changes color

• It bursts with a loud noise
