Question

When water falls from height, some of the energy is used as sound energy after it hurts the floor hardly :) ..... so why only sound energy? Why not heat energy, why not light energy? ..

Answer 1

My guess: Is it because : Metals are sonorous ...?

Answer 2

@TuringTest @calculusfunctions @ParthKohli

Answer 3

Yeah, that works if you are hitting water on metal.

Answer 4

If we hit on non metal then? Will the voice not be produces...

Answer 5

*produced

Answer 6

No... not too much.

Answer 7

What chapter is this question from?

Answer 8

I was just seeing the photos of water fall, and came to this quest. , this is basically related to "conservation of energy law" I think.

Answer 9

So if we strike it on graphite, I think noise will be produced, what do you think ?

Answer 10

Yeah, you could say that...

Answer 11

So, why noise this time? Graphite is a polymorph of Carbon and Carbon is a non metal i.e. non-sonorous.

Answer 12

I have a feeling that water is (or if not, can be) used for heat energy because of its friction... :|

Answer 13

This whole question confuses me.
The best answer I can give is: look at the source of each type of energy.
Heat energy comes from increased molecular kinetic energy. The molecular increase in velocity is relatively negligible in terms of temperature for falling water.
Light energy comes from electrons changing their orbitals. There is no such action taking place with falling water.
Hence falling water generally dissipates energy through waves of pressure in the air, which is sound.
This is true for any substance that does not react with water chemically. I don't know how we started talking about metal....

Answer 14

I completely agree with @TuringTest (this time without sir ;) ... I asked my brother he said

"OK, so just put water sweetly on floor, experienced any sound , NO, that's the answer. And also how you took floor as exactly a "metal" and the guess : Metals are sonorous , is absolutely wrong since sonorous means a kind of sound like that of a bell, hit a plastic on your hand you will experience sound but you will not experience any kind of sound that of a bell... hence they are said to be non-sonorous. "

Answer 15

@SheldonEinstein It's not like non-metals don't produce a sound.
Sonority is a physical property by which metals produce a RINGING SOUND.

Answer 16

I'm sorry, I entered that answer ^^ 10 minutes late because something seems wrong with OS.

Answer 17

@ParthKohli the same mentioned above in my comment :) , I am first this time ...

Answer 18

lol not fair :(

Answer 19

btw do you both agree with my comment ... @TuringTest @ParthKohli
lol @ParthKohli :)

Answer 20

Yes

Answer 21

Yes, i had a problem with OS too
I was gonna say, as far as metals, sodium would produce a lot more light and heat energy being in contact with water.

Answer 22

@TuringTest , please see my above comment (that is large one) , do you agree with it?

Answer 23

I think I have to go for 10-15 minutes,sorry

Answer 24

yes your comment makes sense
I have to go for the night
goodnight all!
