Science IQ Test

[ChemEngineer]

The answers are incredible and speak to the properties of water as so brilliantly designed by Nature's God, as He is called in our Declaration of Independence, written by Christian men of wisdom and integrity.

Twenty-nine of the fifty-six signatories to the Declaration of Independence were graduates of seminary schools.
The great majority of the rest were Christian leaders who spoke boldly about their Christian faith.

The answer is 0.5079 ounces of ice.



Water has a heat capacity of 4.18 J/g C degree

Gold has a heat capacity of 0.129 J/g C degree

The heat of fusion of water is 80 times the heat capacity of water, so one gram of gold will cool down 100 degrees C with the loss of 12.9 Joules. Ice will melt absorbing 4.18 J x 80 per gram or 334.4 J without changing temperature!

The ratio of 12.9 to 334.4 or .038576 will apply to any respective quantity of grams of gold cooling from100 C and ice just melting without even changing temperature. But a troy pound of gold is 373.24 grams, which at 100 C requires 4,814.796 joules to be absorbed.

4,814.796 J divided by 334.4 J/g = 14.398 g of ice

14.398g/ 453.59 g/pound = .031743 pound

.031743 pound of ice at 0 to cool it. .031743 times 16 ounces is 0.5079 ounces of ice.

453.59 g per avoirdupois pound

373.24 g per troy pound

avoirdupois vs troy? LOL!

Thanks.

Thomas Jefferson on Christianity.
“There is not one redeeming feature in our superstition of Christianity. It has made one half the world fools, and the other half hypocrites.”
