#2. Assume that your new temperature scale is based on ammonia, NH3. On the Celsius scale, ammonia has a melting point of -77.7?C and a boiling point of -33.4?C, but on your new scale calibrated in units of degrees ammonia, ?A, you define ammonia to melt at 0 ?A and boil at 300?A. How does your ammonia degree compare in size with a Celsius degree? How does an ammonia degree compare in size with a Fahrenheit degree? What are the melting and boiling points of water on the ammonia scale? What is normal human body temperature (98.6 ?F) on the ammonia scale?

You are working as a research assistant for a professor whose research area is thermodynamics. He points out to you that Daniel Fahrenheit used the best estimate of normal human body temperature as one of the points in defining the original Fahrenheit temperature scale. On the revised scale we now use, normal human body temperature is 98.6°F. Your professor proposes a new scale on which normal human body temperature would be exactly 100°N, where the unit °N is a degree on the New scale. The temperature of freezing water would be 0°N, as on the Celsius scale. Your professor asks you to determine the following temperatures on his new scale:

(a) absolute zero,

(b) the melting point of mercury (−37.9°F),

(c) the boiling point of water, and, for publicity at his expected future press conference,

(d) the highest recorded air temperature on the Earth’s surface. 134.1°F on July 10, 1913, in Death Valley, California.
