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.

Describe the process that occurs when liquid water is heated.

Why can't water go any hotter than 100 degrees Celsius in this context?
