Energy TN 5th Grade

Which of these is the best example of potential energy?

• a ball rolling on a soccer field 
• a boulder sitting on top of a steep hill 
• a marble at rest on the floor                       
• a person riding a bicycle on a flat surface

During a heat transfer demonstration, students observed water being pumped around a closed loop in an engine. The moving water carries heat from the hot engine to the radiator.

Which type of heat transfer is involved when the cooler water absorbs heat while in contact with the hot engine?

• convection
• conduction
• insulation
• radiation

A student on a snow board is at the top of a hill.  

At which point does the student have the greatest potential energy?

• 1
• 2
• 3
• 4

The picture shows some food being heated in a pan.  
Heat is transferring from the pan to the food through which process?

• convection
• radiation
• conduction
• insulation

A person rides a bicycle over a small hill as shown below.  

At what point did the bicycle have the most potential energy?

• W
• X
• Y
• Z

A fireplace is shown in the picture. What is the main process that transfers heat upwards through the chimney?

• convection
• conduction
• radiation
• insulation

Water is boiling in a pan. Most of the heat is transferred from the bottom of the water to the surface of the water. This transfer of energy occurs through which process?

• Conduction
• Convection 
• Radiation
• Insulation

An airplane is slowing down and flying lower as it prepares to land at an airport. Which statement best describes the energy of the airplane?

• The kinetic energy decreases, and the potential energy decreases.
• The kinetic energy decreases, and the potential energy increases.
• The kinetic energy increases, and the potential energy decreases.
• The kinetic energy increases, and the potential energy increases.

A camper cooks a pot of stew over a fire as shown. At which location is heat from the fire mainly transferred by radiation?

• 1
• 2
• 3
• 4

A teacher placed a metal spoon in a container of water with a temperature of 37°C. Then the teacher measured the temperature of the spoon in the water for 5 minutes.   Based on the data, which best explains how energy was transferred between the metal spoon and the water?

• Heat from the water transferred to the spoon by radiation.
• Heat from the water transferred to the spoon by conduction.
• Heat from the spoon transferred to the water by radiation.
• Heat from the spoon transferred to the water by conduction.
