I will like to start refreshing my memory on these subject. so, every week i'll asking one question in physics and chemistry.
With little gift to anyone who provide the correct answer.
Physics &
Chemistry
i remember back in back in school days
So, the question how physics and chemistry do we have on bitcoins talk forum?
Heat of Fusion of H2O => Hf = 334 J /g
=> q= m Hf
If, the above equation is true
=>Then,what is the amount of energy will be required to create 100 btc and at what temperature?
All answer's must be express in equation
Thanks
Arlene

Transactions must be included in a block to be properly completed. When you send a transaction, it is broadcast to miners. Miners can then optionally include it in their next blocks. Miners will be more inclined to include your transaction if it has a higher transaction fee.

what is 'q'? can you explain?
and the amount of energy and the temperature rate to create 100 btc is ever increasing and requiring longer time as the bitcoin block halves, i believe this kind of question or clue has almost no model answer, no idea.

out of ability to use the signature, i want a new ban strike policy that will fade the strike after 90~120 days of the ban and not to be traced back, like google | email me for anything urgent, message will possibly not be instantly responded
i am not really active for some reason

I made the following assumptions.
1) you want to know how much ice we could melt with the energy required to create 100 BTC
2) you would accept an average value since Bitcoin generation is probabilistic
3) we would assume the latest available technology for energy requirements
4) the ice we are melting begins at STP (standard temperature and pressure)
one block = 25 BTC
100 BTC = 4 blocks
average number of hashes to solve a block = difficulty * 232
average number of hashes to solve four blocks = 4 * difficulty * 232
Antminer S7 requires 1210 W to generate 4.86 Thashes/s OR
1210 J/s
--------
4.86X1012 h/s
= 2.4897119341563786008230452674897 X 10-10 Joules per hash
current Bitcoin difficulty is 178678307672
average number of hashes to solve four blocks = 4 * 178678307672 * 232
average number of hashes to solve four blocks = 3069669951823463579648
average energy required to create 100 BTC = 3069669951823463579648 hashes X 2.4897119341563786008230452674897 X 10-10 Joules per hash
average energy required to create 100 BTC = 764259391297.6113027518683127572 Joules
Given Heat of Fusion of H2O => Hf = 334 J /g
q = m Hf
from the average energy required to generate 100 BTC know that q = 764259391297.6113027518683127572
rearranging the HF equation to solve for mass we get
m = q / Hf
m = 764259391297.6113027518683127572 Joules / 334 Joules/gram
m = 2288201770.3521296489576895591533 grams
m = 2288.201770352129 Tonnes
Therefore generation of 100 Bitcoins with sufficient Antminer S7(s) at current difficulty would melt approx. 2288 Tonnes of ice at 0 degrees C.

Well, did I win? Seeing as there were no other entries I must be in the running at least. What more do I need to do to win the coins?

I have to say I am going to have ht better answer of all!! The answer is, "WAY TO MUCH" to make it worth your time to mine alone. I also checked over the answer above and I have to agree with what they have written.

Shit, back in the day I would've calculated for fun the freezing of water from X o given the same parameters, but now I'm mostly at a lost as to what the fuck you just did. But, give me a couple hours, and I believe I could be up to speed once again. |

Cross check your eqn. & eqv. don't you think you omitted something or made mistake when cross you cross-multiply and made subject BTCx to BTCy ? Thanks Arlene |

If not, perhaps you could write this post in your native tongue. If I can't understand it, I have a friend who will. If English is your native tongue, please don't say anything else. I will simply concede my prize. |
