Determine the weight of ice melted at 00C by the heat liberated when 100 grams of steam at 1000C condenses to liquid.
Heat of vaporization = 540 cal/g
Heat of fusion = 80 cal/g.
The strings:
S7P1A15 (containership - mass)
The math:
Pj Problem of Interest is of type containership. It is the mass of the melted ice that is of interest eventhough heat energy is operative.
Heat Of Vaporization: the quantity of heat required to vaporize 1 gram of a liquid substance at its boiling point at constant temperature.
Heat Of Fusion: the quantity of heat required to liquefy 1 gram of a solid substance at its melting point at constant temperature.
Amount of heat liberated by condensation 100 grams of steam at 1000C
= 540 x 100 = 54000 cal
Amount of heat required to melt 1 g of ice at 00C = 80 cal
So, weight of ice melted at 00C by 5400 cal = 54000/80 = 6.75 grams.
The point . is a mathematical abstraction. It has negligible size and a great sense of position. Consequently, it is front and center in abstract existential reasoning.
