Balloon over candle

The video tutorial demonstrates the effects of heat on balloons filled with different substances. A gas-filled balloon pops when exposed to a flame due to the rubber burning and gas escaping. In contrast, a water-filled balloon does not pop because the water absorbs the heat, keeping the rubber cool. The tutorial further explains that water can only reach a maximum temperature of 100 degrees Celsius before turning into vapor, illustrating the concept of heat transfer and boiling point.

What causes the balloon filled with gas to pop when exposed to a flame?

• The gas inside the balloon expands.

• The rubber melts due to the heat.

• The gas inside the balloon ignites.

• The rubber contracts due to the cold.

Why does the balloon filled with water not pop when exposed to a flame?

• The rubber is thicker.

• The water absorbs the heat, keeping the rubber cool.

• The water evaporates quickly.

• The flame is not hot enough.

What role does the water play in the balloon experiment?

• It makes the balloon heavier.

• It increases the pressure inside the balloon.

• It changes the color of the balloon.

• It acts as a coolant, absorbing the heat.

At what temperature does the water inside the balloon start to boil?

• 120 degrees Celsius

• 110 degrees Celsius

• 100 degrees Celsius

• 90 degrees Celsius

Why can't the water inside the balloon get hotter than 100 degrees Celsius?

• The rubber prevents further heating.

• The flame is not strong enough.

• The water turns to vapor at 100 degrees Celsius.

• The balloon bursts before reaching higher temperatures.
