2025 Energy/GEM Remedial Retake Review

1. The process by which hot and cold air (fluid) are transferred in the atmosphere is ___________________

• conduction
• radiation
• convection
• solar energy

2. Which is an example of nuclear energy being converted into heat and light energy?

• The Sun
• A Volcano
• A Rocket Engine
• A Coal Burning Furnace

3. Maria's father started a fire in the fireplace. He crumpled some paper, lit a match and soon the logs were burning. In this case, the stored chemical energy in the logs was changed into _____________________

• electrical energy
• heat and light energy
• mechanical energy
• electrical and heat energy

4. The process of heat radiation is the ONLY method of heat transfer that can occur _________________

• through space
• through glass
• through air
• all of the above

5. David turned on the television. The electrical energy transformed into __________________

• Light only
• light and sound only
• sound ony
• light, sound, and heat

6. Conduction occurs more easily between solids and liquids and not in gases because ______________________.

• farther apart and move faster
• closer together and move faster
• further apart an move more slowly
• closer together and move more slowly

7. The name of heat transfer between two solids which are in direct contact or touching one another is_______

• conduction
• convection
• radiation
• conservation

8. Energy can be changed from one form to another. Changes in the form of energy are called energy conversions. In an automobile engine, the battery is a form of ____________ energy that is converted to electrical energy. The electrical energy is then converted to ________________ energy which is also converted to ________________ energy in the motor.

• Heat ---- Chemical----- Mechanical
• Chemical ------ Mechanical ------- Heat
• Mechanical -------- Heat -------- Chemical
• Chemical --------- Nuclear --------- Mechanical

9. What type of heat transfer is used to fry an egg in a pan and how can you tell?

• It is conduction because the egg gets cooked
• It is conduction because the egg is touching the pan
• It is convection because you put oil in a frying pan to cook it
• It is convection because you can feel the heat a few inches away from the pan.

10. Which would be best categorized as heat transfer by conduction?

• A hot air balloon
• Cooling a burn on your hand by running cold water on your hand
• Feeling the heat from a light bulb with your hand when touching the bulb
• Feeling the heat from light bulb while holding your hand 6 inches away from the bulb.
