Heat Transfer Quiz

What is the temperature at which rubber begins to melt?

• 150 degrees Celsius

• 80 degrees Celsius

• 120 degrees Celsius

• 100 degrees Celsius

Why does a balloon filled with water not pop when a flame touches it?

• Because water has a lower specific heat capacity than rubber

• Because water absorbs the thermal energy of the flame

• Because rubber is a better conductor of heat than water

• Because water evaporates when heated

What is the specific heat capacity of water?

• 2000 joules per kilogram degree Celsius

• 3500 joules per kilogram degree Celsius

• 4200 joules per kilogram degree Celsius

• 1600 joules per kilogram degree Celsius

Why does the rubber balloon pop when a flame touches it?

• Because the rubber has a high specific heat capacity

• Because the rubber is resistant to heat

• Because the rubber is a good conductor of heat

• Because the rubber weakens quickly

What happens to the temperature of the rubber balloon when a flame touches it?

• It remains the same

• It increases rapidly

• It decreases

• It increases slowly

How does the specific heat capacity of water affect its ability to absorb heat?

• It increases its ability to absorb heat

• It has no effect on its ability to absorb heat

• It makes it impossible to absorb heat

• It decreases its ability to absorb heat

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

• Because the rubber has a low specific heat capacity

• Because the rubber is a good conductor of heat

• Because the water evaporates
