Thermal Energy Transfer Quiz-7th

Brennan turned on a lamp with a bare lightbulb. Cierra held a thermometer about 10 cm away from the middle of the lightbulb. The thermometer showed that the temperature was increasing. Brennan then placed a book between the lightbulb and the thermometer for 5 minutes. Which is the BEST prediction for what will happen next?

• Both the book and the thermometer will decrease in temperature.

• The cover of the book nearest to the lightbulb will warm up and the temperature reading on the thermometer will not change.

• The thermometer will continue to show an increase in temperature and the book’s temperature will not change.

• The cover of the book nearest to the lightbulb will warm up and the temperature reading on the thermometer will decrease.

A student used a metal spoon to stir some soup as it heated up in a saucepan on the stove. The student got distracted and left the spoon sitting in the soup with its handle against the rim of the saucepan. Will the spoon likely be hot when the student returns, and what is the reasoning?

• Yes, due to radiation of heat from the stove.

• No, due to the convection current from the soup.

• Yes, due to conduction of heat through the metal saucepan.

• No, due to the poor conduction of heat through the spoon handle.
