Hello everyone.
I hate to be a burden,
and I hate to sound as if I'm too lazy to do my homework-
'cause I'm not,
but this science homework.. I just don't get!

I am doing energy conversions, and I have to put an example for a lot of energy conversions.
I have to put an example for an energy conversion of:
Heat to sound
Heat to chemical
light to mechanical
sound to heat
sound to light
sound to sound
sound to chemical
sound to mechanical
chemical to sound

And again, if I sound annoying by asking for help, I'm sorry but I've been stuck on this jazz.
Any help is appreciated. ❤️

Good luck! 😃

Lol, dat face! xD
Thank you. 😊

@froggytails
i'll give this a shot lol
the sound of sizzling bacon when you cook it! yum 😋
the sun's gas
solar panels
idk about those sound ones but for the last one
rice crispie ceral going snap! crackle! pop! in your bowl of milk

...when in doubt, use google!
good luck on those tests

@hybridrainbow

Thank you for your help. ❤️

@yingtai

Thank you, but I couldn't find any of the conversions I need...

@froggytails Oops. Maybe I should have looked at it more :|

Most of the sites say that sound is already a type of that energy o_o Good luck on finding the rest ^^

@yingtai

Yeah..
Thank you. ^^

@froggytails
I spent 10 minutes to do some research for you!~ 😸
There are some parts that I'm not really sure of ^^

Heat to sound
> Taking care of waste heat from radar, and also producing a portable source of electrical energy which you can use in the battlefield to run electronics by converting Heat to Sound.

Heat to chemical
> (usually found in multiple transformations)
> [[For example, the mechanical energy used to strike a match is transformed first to thermal energy. ]] The thermal energy causes the particles in the match to release stored chemical energy, [[which is transformed to thermal energy and the electromagnetic energy you see as light.]]

Light to Mechanical
> An electric motor, a solenoid, an electromagnet, an electric clock.

Sound to Heat
> High-Intensity Focused Ultrasound (HIFU, or sometimes FUS for Focused Ultrasound) is a highly precise medical procedure that applies high-intensity focused sonic energy to locally heat and destroy diseased or damaged tissue through ablation.

Sound to Light
> Light (visible spectrum) is an electromagnetic wave.
> A microphone converts sound into EM waves. This is how all modern broadcast is achieved, through converting signals into EM waves and then transmitting those waves.

Sound to Sound
> Sound energy is converted into electrical energy and transmit from one place to another - like the radio & phone. After that the electric energy is transformed back to sound energy that we can hear.

Sound to Chemical
> It is possible, pretty inefficient though, sound waves don't travel too far and don't have all that much energy.
> Ultrasonic waves can also break fragile chemical bonds.

Sound to Mechanical
> Active in Hearing Function.
> Sound in the environment is enhanced by the resonances in the outer ear and converted to mechanical energy by the eardrum.
The motion of the fluids within the cochlea is a hydraulic form of energy
The fluid movement distorts the hair cells which sit on the basilar membrane
The hair cells convert the mechanical/hydraulic energy into electrical impulses
The electrical impulses are transmitted through the nervous system to the brain where they are finally perceived and interpreted as sound.

Chemical to Sound
> Chemical energy stored in the fireworks is converted to kinetic energy to send the rocket skyward; some compresses the air rapidly, producing sound and still more energy is transformed into light of many colours.

@ostrichowl

Omg-
thank you so much for doing all that work for me,
and spending time doing it.
You are amazing! 😃
Thank you! ^^

@froggytails Don't worry, I also had benefited from it~
Science is great 😃 I need to feed my brain once in a while ^^
You're welcome 😸

Topic moved to the correct section.

@ostrichowl

Your brain must be full now. x3

Oh hey-
if you don't mind,
can you explain what you put for heat to sound?
You put:
"Taking care of waste heat from radar, and also producing a portable source of electrical energy which you can use in the battlefield to run electronics by converting Heat to Sound."

But I guess I still... don't grasp it.
Are you saying that an example of heat to sound would be something that people use on the battlefield(war)?

@froggytails

Apparently heat can be converted to electricity through converting it to sound first. I'm not sure with this one though because I believe this is part of a feasibility study (or probably new technology whatsoever) of conversion of heat to sound (using thermoacoustic prime movers) and then converting sound to electricity (using piezoelectric devices).

And by battlefield, they probably meant the industry because it is an efficient source of renewable energy from the waste heat.

Here are my sources:

Is this the only part you are confused of? 😸

@ostrichowl

Oh okay, thank you. 😸
Yeah, that was the only part I was confused about. ~
