Question

review it!
select the statement(s) that are true about energy and conduction.
nuclear energy is the energy of moving things.
conduction is the transfer of thermal energy through direct contact.
popcorn popped in a pan on a stove top is an example of conduction.
thermal energy transfers from warmer objects to cooler objects.
thermal energy is the amount of kinetic energy in the particles of a substance.

Explanation:

1. Analyze "Nuclear energy is the energy of moving things": Kinetic energy is the energy of moving things, while nuclear energy is energy stored in atomic nuclei. So this is false.
2. Analyze "Conduction is the transfer of thermal energy through direct contact": By definition, conduction is thermal energy transfer via direct contact (e.g., a spoon in hot soup gets hot). This is true.
3. Analyze "Popcorn popped in a pan on a stove top is an example of conduction": The stove heats the pan (direct contact), and the pan heats the popcorn (direct contact), so this is conduction. True.
4. Analyze "Thermal energy transfers from warmer objects to cooler objects": Thermal energy (heat) naturally flows from higher temperature (warmer) to lower temperature (cooler) objects. True.
5. Analyze "Thermal energy is the amount of kinetic energy in the particles of a substance": Thermal energy is related to the kinetic (and potential) energy of particles in a substance. The total kinetic energy of particles contributes to thermal energy. True (note: more accurately, it's the total internal energy related to particle motion, but this statement is a simplified correct description here).

Answer:

• Conduction is the transfer of thermal energy through direct contact.
• Popcorn popped in a pan on a stove top is an example of conduction.
• Thermal energy transfers from warmer objects to cooler objects.
• Thermal energy is the amount of kinetic energy in the particles of a substance.
