A quantity of steam (275g) at 110 degrees C is condensed and the resulting water is frozen into ice at 0 degrees C. How much heat was removed? Solve using kcal. Please solve by showing steps, I'm getting lost somewhere!
Homework Answers
A mean calorie is 1?100 of the amount of energy required to warm one gram of air-free water from 0
1. Change temp from 110 to 100.
2. Convert steam into water.
3. Change temp from 100 to 0.
4. Convert water into ice.
1. 275 * .48 * 10 = 1320
2. 275 * 540 = 148500
3. 1 * 275 * 100 = 27500
4. 275 * 80 = 22000
1320 + 148500 + 27500 + 22000 = 199320 cal = 199.32 kcal

A 0.750 L quantity of steam condensed on a surface (after boiling). a. Approximately how much heat has evolved? By using the change in enthalpy of vaporization is 40.7 kjmol^-1 for water at 100 C, 85.0 C as the temperature of the surface on which the steam condenses, and 4.21 J g^-1 C^-1 as the average specific heat of liquid water in the temperature ranges 85C to 100C. b. How much heat has evolved in this case? Show your work.

Burns produced by steam at 100 degree C are much more severe than those produced by the same mass of 100 degree C water. To verify this, answer the questions below. Specific heat of water = 1.00 kcal/(kg degree C); heat of vaporization = 539 kcal/kg; specific heat of human flesh = 0.83 kcal/(kg degree C). Calculate the quantity of heat that must be removed from 7.00 g of 100degree C water to lower its temperature to 45.0degree C. kcal...
