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.
A hot air balloon contains air that expands as it is heated. Which is the main type of thermal energy transfer that causes a hot air balloon to rise?
radiation
convection
conduction
evaporation
In the image below, which is the main type of thermal energy transfer that causes the cat to feel warm?
radiation
convection
conduction
combustion
The wind results from the uneven heating of the Earth's surface. Which type of energy transfer warms Earth's surface?
radiation
conduction
convection
condensation
The wind results from the uneven heating of the Earth’s surface. Which type of energy transfer occurs when warm areas of Earth’s surface heat the air in contact with the ground?
radiation
conduction
convection
absorption
The wind results from the uneven heating of the Earth’s surface. Which type of energy transfer occurs when warm air rises and forces cooler air masses downward?
radiation
conduction
convection
equalization
A thin plastic bag containing 200 mL of 60°C water is submerged in a beaker containing 200 mL of 80°C water. Which BEST describes what happens to the water temperature in the bag and the beaker?
The water bag’s temperature increases and the beaker water’s temperature decreases.
The water bag’s temperature increases and the beaker water’s temperature stays the same.
The water bag’s temperature stays the same and the beaker water’s temperature decreases.
The water bag’s temperature decreases and the beaker water’s temperature decreases.
A thin plastic bag containing 200 mL of 60°C water is submerged in a beaker containing 200 mL of 80°C water. The experiment is left to sit at room temperature, 25°C, for 12 hours. Which is the BEST prediction for the temperature of the water in the bag and beaker after this time?
They will both be at 70°C.
They will both be at 60°C.
They will both be at 35°C.
They will both be at 25°C.
A thin plastic bag containing 200 mL of 60°C water is submerged in a beaker containing 200 mL of 80°C water. How could this experiment BEST be modified to reduce the exchange of heat between the surroundings and the experiment system?
A polystyrene foam container could replace the plastic bag.
A polystyrene foam container could replace the beaker.
A steel container could replace the plastic bag.
A steel container could replace the beaker.
