Answer to Problem 1P

The absolute zero in the new scale is 738°N .

Explanation of Solution

Given info: The normal human body temperature in degree Fahrenheit is 98.6°F . In the new scale the normal body temperature and freezing point of water is 100°N and 0°N respectively. The melting point of mercury is 37.9°F . The highest temperature is 134.1°F .

Write the expression to convert the temperature scale.

N=aF+b (1)

Here,

N is the temperature in °N .

a,b are constants.

F is the temperature in degree Fahrenheit.

Substitute 98.6°F for F and 100°N for N in equation (1).

100°F=a(98.6°F)+b (2)

The freezing point of water in degree Fahrenheit is 32°F .

Substitute 32°F for F and 0°N for N in equation (1).

0N=a(32°F)+b (3)

Solve equation (2) and (3).

a=1.5b=48.04

The temperature of absolute zero in degree Fahrenheit is 460 .

Substitute 460 for F , 1.5 for a and 48.04 for b in equation (1).

N=1.5(460)+(48.04)=738N

Conclusion:

Therefore, the absolute zero in the new scale is 738°N .

Answer to Problem 1P

The melting point of mercury in new scale is 105°N .

Explanation of Solution

Given info: The normal human body temperature in degree Fahrenheit is 98.6°F . In the new scale the normal body temperature and freezing point of water is 100°N and 0°N respectively. The melting point of mercury is 37.9°F . The highest temperature is 134.1°F .

Write the expression to convert the temperature scale.

N=aF+b (1)

Substitute 37.9 for F , 1.5 for a and 48.04 for b in equation (1).

N=1.5(37.9)+(48.04)=105

Conclusion:

Therefore, the melting point of mercury in new scale is 105°N .

Answer to Problem 1P

The boiling point of water in new scale is 270°N .

Explanation of Solution

Given info: The normal human body temperature in degree Fahrenheit is 98.6°F . In the new scale the normal body temperature and freezing point of water is 100°N and 0°N respectively. The melting point of mercury is 37.9°F . The highest temperature is 134.1°F .

The boiling point of water in degree Fahrenheit is 212 .

Write the expression to convert the temperature scale.

N=aF+b (1)

Substitute 212 for F , 1.5 for a and 48.04 for b in equation (1).

N=1.5(212)+(48.04)=270

Conclusion:

Therefore, the boiling point of water in new scale is 270°N .

Answer to Problem 1P

The highest recorded air temperature on Earth’s surface in new scale is 153°N .

Explanation of Solution

Given info: The normal human body temperature in degree Fahrenheit is 98.6°F . In the new scale the normal body temperature and freezing point of water is 100°N and 0°N respectively. The melting point of mercury is 37.9°F . The highest temperature is 134.1°F .

Write the expression to convert the temperature scale.

N=aF+b (1)

Substitute 134.1 for F , 1.5 for a and 48.04 for b in equation (1).

N=1.5(134.1)+(48.04)=153

Conclusion:

Therefore, the highest recorded air temperature on Earth’s surface in new scale is 153°N .
