Hint:Temperature is the measure of degree of hotness or coldness of a body. A scale of temperatures is made on the basis of two standard temperatures which is universally accepted. These are the upper and lower fixed points. The lower fixed point is the temperature at which the ice melts and the upper fixed point is the temperature at which the water boils. The temperature at which the ice melts is called the melting point and the temperature at which the water boils is called the boiling point and both are fixed points and never change.
Complete step by step answer:
Two most commonly used scales for measuring temperature are Celsius Scale and Fahrenheit Scale. In the Fahrenheit scale, water boils at a temperature of ${212^ \circ }{\text{ F}}$and ice melts at a temperature of ${32^ \circ }{\text{ F}}$. Therefore, the upper fixed point of the Fahrenheit scale is ${212^ \circ }{\text{ F}}$ and the lower fixed point is ${32^ \circ }{\text{ F}}$.
The difference between the upper fixed point and lower fixed point gives the number of divisions in the scale. Number of divisions in the Fahrenheit scale is
$(212 - 32) = 180{\text{ parts}}$
The difference between the two points is divided into $180$ equal divisions. In other words, each division measures a temperature difference of ${1^ \circ }{\text{ F}}$.Fahrenheit scale is used in clinical (doctor’s) thermometers.
Hence, the correct answer is option A.
Note:In Celsius Scale, the upper fixed point is ${100^ \circ }{\text{ C}}$ and lower fixed point is ${0^ \circ }{\text{ C}}$. The number of divisions in the Celsius scale is $100{\text{ parts}}$. Each division of Celsius Scale measures a temperature difference of ${1^ \circ }{\text{ C}}$.
