Title: (Hf = 334 J /g)Your Chance To Earn 0,01147 BTC Answering Physic Question Post by: arlene05973 on April 20, 2016, 02:17:47 PM 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 Title: Re: (Hf = 334 J /g)Your Chance To Earn 0,01147 BTC Answering Physic Question Post by: lottery248 on April 21, 2016, 12:39:47 PM 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.

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.

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.

But, give me a couple hours, and I believe I could be up to speed once again.

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. |
