Air temperature rises from a morning low of 42°f to an afternoon high of 70°f. (a) express these temperatures in °r, k, and °c. (b) determine the temperature change in °f, °r, k, and °c from morning low to afternoon high. (c) what conclusion do you draw about temperature change for °f and °r scales? (d) what conclusion do you draw about temperature change for °c and k scales?

Explanation:

The Fahrenheit temperature conversion formulas are:

a) Using the previous equations we obtain the values of the temperatures in all scales:

b)

c) The temperature change in these scales corresponds to the same number (28). So, a change of one degree  in Rankine scale is equal to a change of one degree  in Fahrenheit scale.

d)The temperature change in these scales corresponds to the same number (15.556), So, a change of one degree  in Celsius scale is equal to a change of one degree  in Kelvin scale.

step-by-step explanation:

we are given

we have to simplify it

firstly, we will factor it

now, we can cancel like terms

now, we can combine it

so, we get
