101.9 – Read Faq
Ken asks…
What was the initial volume of the system if the internal energy of the system decreased by 101.9 J?
As a system increases in volume, it absorbs 52.5 J of energy in the form of heat from the surroundings. The piston is working against a pressure of 0.500 atm. The final volume of the system is 58.0 L.
Staff Member Said:
Assume in constant temperature condition,
W = P (V' - V)
-101.9 + 52.5 = (0.5 * 1.01 * 10^5) (58/1000 - V)
V = 0.058978217821782178218 m³
V = 58.97 L
Nancy asks…
what is the title of this song and the artist please, it is usually on the radio station 101.9 the mix?
It something like this: "Hey mama hey mama; but I'll be back on my feet someday; I love you I love you I love you. That's all I remember from the song and the lyrics are not in the right order listed above. It came out either 2 months or less. Thank you guys. 5 stars awarded to whomever is the first one to get it right.

Sandy asks…
How do I make mp3 files louder without affecting the quality?
I have an mp3 player and I'd like to adjust the volume. I know i'll never get them as loud as a nightclub but i'd like them as loud as possible without any quality distortion. I'm currently using MP3Gain but sometimes when I adjust the volume it kinda "crackles"?
I have the volume adjustment set to 101.9 db. The default is 89.0.
Please help

You need better headphones, the higher quality the headphones, the better the sound.
Sounds like your headphones are "maxing" out.
Got a pair of Phillips headphones for around $10 US and they will push 120 db easy.
