Determine the heat required to accomplish the following processes:

(a) heat 1 mole of liquid water from room temperature (25 °C) to its boiling temperature (100 °C at 1 atm presssure).

(b) vaporize the water at 100 °C

(c) heat the steam to 150 °C

(d) now condense the 150 °C steam and cool it to the initial temperature, 25 °C.

(e) Notice which of the steps in the heating process above involves the most heat. Provide an explanation.

1. You are given a quantity of a volatile liquid substance and asked to determine its molecular weight. To do that, you place a sample of the liquid in a 200.0-mL flask and submerge the flask in a boiling water to vaporize all of the liquid. The vapor fills the flask and the excess escapes,. Now you cool the flask so that all the vapor in it condenses, and you weigh the flask and liquid. After you subtract the mass...
