Question

science quick check - energy transformations (sol 5.2)
directions: use the words from the boxes below to fill in the blanks and empty boxes.
radiant destroyed sound electrical currents transform
energy cannot be created or destroyed; however, it can transform from one form into another, to do work. (work means when a force acts upon an object, it causes that object to move in the direction of the force.) energy can take many forms such as thermal, radiant, sound, mechanical, and electrical.
energy can be moved from place to place by moving objects, or through sound, light, or electric ______.
energy can change forms but cannot be created or destroyed out of nowhere, and the electrical energy did not just disappear. if a stove is turned on, the electrical energy transforms into thermal energy. that thermal energy did not just appear.
examples of energy transformations:

object	start	end
tea kettle whistling	thermal	electrical
using a blender		mechanical

Explanation:

Filling the Blanks (First Paragraph):

1. The first blank: From the law of conservation of energy, energy cannot be created or destroyed, so the first blank (after "cannot be created or") should be "destroyed".
2. The second blank: The sentence says "it can ____ from one form to another to do work". The word from the box is "transform", as energy transforms from one form to another.
3. The third blank: The sentence "Energy can be moved from place to place by moving objects, or through sound, light, or electric ____." The word from the box is "currents" (electric currents).

Filling the Energy Transformation Table:

• Solar Panel: A solar panel takes radiant energy (from the sun) and transforms it into electrical energy. So "start" is "radiant", "end" is "electrical".
• Tea Kettle Whistling: A tea kettle when whistling - first, the thermal energy (from the heated water) causes the whistle to produce sound, but also, if we consider the process, maybe the start is "thermal" (heat in the kettle) and the end - wait, the table has "start" and "end". Wait, the tea kettle whistling: when the kettle is heated (thermal energy), the whistling is sound energy, but also, maybe the electrical energy? No, the tea kettle whistling - maybe the start is "thermal" (heat) and the end is "sound"? Wait, the given "end" for tea kettle whistling is "electrical"? No, maybe I misread. Wait the table:

Object | start | end
--- | --- | ---
solar panel | |
tea kettle whistling | thermal | electrical
using a blender | | mechanical

Wait, solar panel: solar panels convert radiant (light) energy to electrical energy. So "start" is "radiant", "end" is "electrical".

Using a blender: A blender uses electrical energy and converts it to mechanical energy (to blend). So "start" is "electrical", "end" is "mechanical".

Final Fills:

First paragraph blanks:

• Energy cannot be created or destroyed; however, it can transform from one form to another to do work. (Work means when a force acts upon an object, it causes that object to move in the direction of the force.) Energy can take many forms such as thermal, radiant, sound, mechanical, and electrical. Energy can be moved from place to place by moving objects, or through sound, light, or electric currents.

Energy Transformation Table:

Object	start	end
tea kettle whistling	thermal	electrical (Wait, maybe the tea kettle whistling: when the kettle is heated (thermal), but the whistling - maybe the process is that the thermal energy causes the water to boil, and the steam creates sound, but also, if the kettle is electric, then electrical to thermal to sound? But the table has "start" as "thermal" and "end" as "electrical" - maybe a typo, but following the given table's "end" as "electrical" for tea kettle whistling, so start is "thermal", end is "electrical".)
using a blender	electrical	mechanical

First Paragraph Answers:

1. destroyed
2. transform
3. currents

Table Answers:

• Solar Panel: start - radiant, end - electrical
• Tea Kettle Whistling: start - thermal, end - electrical
• Using a Blender: start - electrical, end - mechanical

Answer:

Filling the Blanks (First Paragraph):

1. The first blank: From the law of conservation of energy, energy cannot be created or destroyed, so the first blank (after "cannot be created or") should be "destroyed".
2. The second blank: The sentence says "it can ____ from one form to another to do work". The word from the box is "transform", as energy transforms from one form to another.
3. The third blank: The sentence "Energy can be moved from place to place by moving objects, or through sound, light, or electric ____." The word from the box is "currents" (electric currents).

Filling the Energy Transformation Table:

• Solar Panel: A solar panel takes radiant energy (from the sun) and transforms it into electrical energy. So "start" is "radiant", "end" is "electrical".
• Tea Kettle Whistling: A tea kettle when whistling - first, the thermal energy (from the heated water) causes the whistle to produce sound, but also, if we consider the process, maybe the start is "thermal" (heat in the kettle) and the end - wait, the table has "start" and "end". Wait, the tea kettle whistling: when the kettle is heated (thermal energy), the whistling is sound energy, but also, maybe the electrical energy? No, the tea kettle whistling - maybe the start is "thermal" (heat) and the end is "sound"? Wait, the given "end" for tea kettle whistling is "electrical"? No, maybe I misread. Wait the table:

Object | start | end
--- | --- | ---
solar panel | |
tea kettle whistling | thermal | electrical
using a blender | | mechanical

Wait, solar panel: solar panels convert radiant (light) energy to electrical energy. So "start" is "radiant", "end" is "electrical".

Using a blender: A blender uses electrical energy and converts it to mechanical energy (to blend). So "start" is "electrical", "end" is "mechanical".
