(a) Calculate the change in entropy when 1.00 kg of water at 100^o C is vaporized and converted to steam at 100^o C (see Table 17.4). (b) Compare your answer to the change in entropy when 1.00 kg of ice is melted at 0^o C, calculated in Example 20.5 (Section 20.7). Is the change in entropy greater for melting or for vaporization? Interpret your answer using the idea that entropy is a measure of the randomness of a system.
