Chapter 20, Problem 59(choose chapter or problem)
Integrated Concepts
Cold vaporizers pass a current through water, evaporating it with only a small increase in temperature. One such home device is rated at \(3.50 A\) and utilizes \(120 V AC\) with \(95.0 \%\) efficiency.
(a) What is the vaporization rate in grams per minute?
(b) How much water must you put into the vaporizer for \(8.00 h\) of overnight operation? (See Figure \(20.42\).)
Figure \(20.42\) This cold vaporizer passes current directly through water, vaporizing it directly with relatively little temperature increase.
