Chapter 0, Problem 8

(choose chapter or problem)

A 50.0 g sample of pure water is heated from \(10^{\circ} \mathrm{C}\) to \(120^{\circ} \mathrm{C}\).

a. Draw and label a heating curve that represents the different stages of this process.

b. If the specific heat capacity is \(0.49 \mathrm{cal} / \mathrm{g} \cdot{ }^{\circ} \mathrm{C}\) for ice, \(1.0 \mathrm{cal} / \mathrm{g} \cdot{ }^{\circ} \mathrm{C}\) for liquid water, and \(0.50 \mathrm{cal} / \mathrm{g} \cdot{ }^{\circ} \mathrm{C}\) for steam, how much energy is added to a 50.0 g sample of water to raise its temperature from \(10^{\circ} \mathrm{C}\) to \(120^{\circ} \mathrm{C}\)?

c. Use the heating curve and your calculations to determine which part of the process requires the most heat transfer. Explain your reasoning.
