Question: Find the correct option (A) Ice point in Fahrenheit scale is \({32^ \circ }F\) (B) Ice point in ...

Find the correct option
(A) Ice point in Fahrenheit scale is 32∘F{32^ \circ }F
(B) Ice point in Fahrenheit scale is 98.8∘F{98.8^ \circ }F
(C) Steam point in Fahrenheit scale is 212∘F{212^ \circ }F
(D) Steam point in Fahrenheit scale is 252∘F{252^ \circ }F

Explanation

Solution

Here first we have to see what is meant by ice point and steam point in Fahrenheit scale.Then we can see which options are correct and which are not.

Complete step by step answer:
Fahrenheit is a temperature scale mainly found in the United States, where the water freezing point is 3232 degrees and the water boiling point is 212212 degrees.This divides 180180 degrees from the boiling and freezing points of water. Thus, a degree on the scale of Fahrenheit is 1/1801/180of the interval between the freezing point and boiling point. The freezing and boiling points of water are 100100 degrees apart on the Celsius scale. A 1∘F{1^ \circ }F temperature interval is equal to a 5/95/9 degrees Celsius interval.Ice point corresponds to the freezing point if water is equivalent to 0∘C(32∘F){0^ \circ }C({32^ \circ }F),in which pure water and ice are in equilibrium.Steam point corresponds to the boiling point of fresh water equal to 100100 degree Celsius at which water and vapour are in equilibrium.

Hence, from the above discussion we can conclude that options A and C are correct.

Additional information:
Ice point temperature- The temperature under atmospheric pressure at which liquid and solid water is in equilibrium. For determining temperature ranges and for calibrating thermometers, the ice point is by far the most critical fixed point.Freezing point is where a liquid becomes a solid at a temperature. As with the melting point, the freezing point is normally raised by added pressure. In the case of mixtures and for some chemical compounds including fats, the freezing point is smaller than the melting point.

Note: Here we may get confused between the options as all the options appear to be almost the same. But here if we can remember the Fahrenheit scale, then there will not be any confusion.
