Chapter 4, Problem 1AC

The Fahrenheit thermometer scale is

a. more accurate than the Celsius scale.

b. less accurate than the Celsius scale.

c. sometimes more or less accurate, depending on the air temperature.

d. no more accurate than the Celsius scale.

To determine

The accuracy of Fahrenheit thermometer scale in comparision to Celsius scale, from the following options.

More accurate than the Celsius scale.

Less accurate than the Celsius scale.

Sometimes more or less accurate, depending on the air temperature.

No more accurate than the Celsius scale.

Answer to Problem 1AC

Solution:

Option (d) is correct.

Explanation of Solution

Introduction:

Temperature scales are the devices used to find the temperature of the systems or surroundings in thermodynamics. There aredifferent types of scales like Fahrenheit scale, Celsius scale and Kelvin scale.

Explanation:

Reason for the correct options:

The Fahrenheit scale is just as valid asCelsius scale to measure the temperature as the Celsius scale gives their well-defined units. It is because working fluid in both the scales are liquid.

Therefore, option (d) is correct.

Reason for the incorrect options:

In the Fahrenheit scale and Celsius scale, working fluid is same therefore, there isn’t any difference.

Therefore, option (a) and option (b) are incorrect.

The accuracy of Fahrenheit scale does not change with air temperature. Even it is usually used to measure air temperature as well.

Therefore, option (c) is incorrect.

Conclusion:

The Fahrenheit thermometer scale is no more accurate than the Celsius scale.
