Question

summarize it! drag and drop the words or phrases to accurately complete the paragraph. thermal energy always transfers from □ substances. when thermal energy is absorbed by a substance, the particles in that substance □. in the picture at the left, hot dogs are being cooked by boiling them in water over a campfire. the flames transfer thermal energy via □ through electromagnetic waves. the pot transfers thermal energy to the water via □ because the pot and the water are in direct contact with each other. the water transfers thermal energy to the hot dogs via □ because a fluid substance (water) is being used to do the transfer. words to drag: magnetic, slow down, convection, electromagnetic, speed up, warmer to cooler, radiation, conduction, cooler to warmer, radioactive

Answer:

To solve this, we analyze the concepts of thermal energy transfer:

First Blank (Thermal energy direction):

Thermal energy transfers from a warmer substance to a cooler substance (heat flows down the temperature gradient). So the first blank (after "from") is "warmer" and the second (after "to") is "cooler". But looking at the options, the first part of the sentence: "Thermal energy always transfers from [blank] substances. When thermal energy is absorbed...", so the first blank here (the first dropdown) is "warmer to cooler" doesn’t fit, wait—wait, the first sentence: "Thermal energy always transfers from [blank] substances. When thermal energy is absorbed by a substance, the particles in that substance [blank]."

Wait, let's re-express:

1. Thermal energy transfer direction: from warmer to cooler (but the first blank is a single phrase? Wait, the options: "warmer to cooler", "cooler to warmer", etc. Wait, the first sentence: "Thermal energy always transfers from [blank] substances." Wait, no—maybe the first blank is "warmer to cooler" but the options have "warmer to cooler" as a phrase. Wait, the options for the first blank (the first drag-and-drop) are among the left/right boxes. Let's list the options:

Options (from the boxes):

• magnetic, slow down, convection, electromagnetic, speed up,
• warmer to cooler, radiation, conduction, cooler to warmer, radioactive

Step 1: Thermal Energy Transfer Direction

Thermal energy flows from a warmer substance to a cooler substance. So the first blank (after "from") is filled with "warmer to cooler"? Wait, no—the first sentence: "Thermal energy always transfers from [blank] substances." Wait, maybe the first blank is "warmer" and the second (but no, the structure is: "from [blank] substances"—wait, no, the original sentence: "Thermal energy always transfers from [blank] substances. When thermal energy is absorbed by a substance, the particles in that substance [blank]."

Wait, the second part: when a substance absorbs thermal energy, its particles speed up (kinetic energy increases, so they move faster). So the second blank (particles in that substance) is "speed up".

Step 2: Flame to Pot (Energy Transfer)

The flames transfer thermal energy to the pot via radiation (because flames emit electromagnetic waves, i.e., radiation). Wait, no—radiation is via electromagnetic waves. The option "radiation" or "electromagnetic"? Wait, the option is "radiation" (one of the boxes). Wait, the sentence: "The flames transfer thermal energy via [blank] through electromagnetic waves." Wait, no—radiation is the transfer via electromagnetic waves. So "radiation" is the process, and it uses electromagnetic waves. So the first blank (flames to pot) is "radiation"? Wait, no—the option "electromagnetic" is there. Wait, the sentence: "The flames transfer thermal energy via [blank] through electromagnetic waves." So the method is "radiation" (which uses electromagnetic waves), but the option "electromagnetic" is a wave type. Wait, maybe the first blank (flames to pot) is "radiation"? No, the option "radiation" is a box. Wait, let's re-express the sentences:

1. "Thermal energy always transfers from [warmer to cooler] substances. When thermal energy is absorbed by a substance, the particles in that substance [speed up]."
2. "In the picture at the left, hot dogs are being cooked by boiling them in water over a campfire. The flames transfer thermal energy via [radiation] through electromagnetic waves. The pot transfers thermal energy to the water via [conduction] because the pot and the water are in direct contact with each other. The water transfers thermal energy to the hot dogs via [convection] because a fluid substance (water) is being used to do the transfer."

Let’s verify each blank:

• First blank (thermal energy transfer direction): warmer to cooler (heat flows from warmer to cooler).
• Second blank (particles when absorbing energy): speed up (thermal energy increases particle motion).
• Third blank (flames to pot): radiation (flames transfer heat via radiation, which uses electromagnetic waves).
• Fourth blank (pot to water): conduction (direct contact between pot and water).
• Fifth blank (water to hot dogs): convection (fluid (water) transfers heat).

Filling the Blanks:

1. Thermal energy always transfers from \(\boldsymbol{\text{warmer to cooler}}\) substances. When thermal energy is absorbed by a substance, the particles in that substance \(\boldsymbol{\text{speed up}}\).
2. The flames transfer thermal energy via \(\boldsymbol{\text{radiation}}\) through electromagnetic waves.
3. The pot transfers thermal energy to the water via \(\boldsymbol{\text{conduction}}\) (direct contact).
4. The water transfers thermal energy to the hot dogs via \(\boldsymbol{\text{convection}}\) (fluid transfer).

(Note: The exact order of drag-and-drop depends on the blank positions, but the key concepts are:

• Direction: warmer to cooler
• Particle motion: speed up
• Flame to pot: radiation
• Pot to water: conduction
• Water to hot dogs: convection)
