Thermal Properties of Rubber and Water

The video explains the melting point of rubber and the boiling point of water. It demonstrates an experiment where a flame causes an air-filled balloon to pop but not a water-filled balloon. This is due to water's high specific heat capacity, which absorbs the thermal energy, preventing the rubber from reaching its melting point. The video highlights the concept of specific heat capacity and its role in heat transfer.

At what temperature does rubber begin to melt?

• 150 degrees Celsius

• 120 degrees Celsius

• 100 degrees Celsius

• 200 degrees Celsius

What happens when a flame touches a balloon filled with air?

• The balloon remains intact

• The balloon shrinks

• The balloon pops

• The balloon gets blackened

Why does a balloon filled with water not pop when touched by a flame?

• The balloon is thicker

• The rubber is stronger

• The water absorbs most of the thermal energy

• The flame is not hot enough

What is the specific heat capacity of water?

• 5200 joules per kilogram degree Celsius

• 3200 joules per kilogram degree Celsius

• 4200 joules per kilogram degree Celsius

• 1600 joules per kilogram degree Celsius

How does the specific heat capacity of water compare to that of rubber?

• Both have the same specific heat capacity

• Water's specific heat capacity is higher

• Water's specific heat capacity is lower

• Rubber's specific heat capacity is higher

What happens to the temperature of the rubber when the balloon is filled with water and exposed to flame?

• It drops

• It remains constant

• It rises slowly

• It rises quickly

Why does the balloon with water not reach its melting point?

• The flame is not hot enough

• The balloon is thicker

• The water keeps the rubber's temperature below 100 degrees Celsius

• The rubber is heat-resistant
