A 100.0-mL sample of water is heated to its boiling point. How much heat (in kJ) is required to vaporize it? (Assume a density of 1.00 g/mL.)

2 You may want to reference Section 3.7 (Pages 80-87) while completing this problem. Using the values for the heat of fusion, specific heat of water, and/or heat of vaporization, calculate the amount of heat energy in each of the following. Keep in mind that the sign of the heat involved in the state change is ignored.

Use the following values to answer each part. The specifi c heat of water is 1.00 cal/(g · °C); the heat of fusion of water is 79.7 cal/g; and the heat of vaporization of water is 540 cal/g. a. How much energy (in calories) is needed to melt 45 g of ice at 0.0 °C and warm it to 55 °C? b. How much energy (in calories) is released when 45 g of water at 55 °C is cooled to 0.0 °C, and frozen to solid ice at 0.0 °C? c. How much energy (in kilocalories) is released when 35 g of steam at 100. °C is condensed to water, the water is cooled to 0.0 °C, and the water is frozen to solid ice at 0.0 °C?

20.) You want to raise the temperature of ice at 0 degrees Celsius to steam at 110 degrees O Celsius. The specific heat of water is 4.184 J/Cg. The specific heat of steam is 2.01 J/Cg, and the specific heat of ice is 2.03 J/Cg. Ice has a heat of fusion at 334 J/g and water has a heat of vaporization of 2260 J/g. Find the Q for this raise in temperature.
