\nThe temperature change from 240 K to 210 K is 30 K. The corresponding change in degree Fahrenheit is 54\u00b0F, which is option A.
\n<\/section>\n
\nA change in temperature on the Kelvin scale is equal to the same change in temperature on the Celsius scale (\u0394T_K = \u0394T_C). The relationship between a change in Celsius and a change in Fahrenheit is \u0394T_F = (9\/5) * \u0394T_C.
\n<\/section>\n
\nGiven the initial temperature T1 = 240 K and final temperature T2 = 210 K, the change in Kelvin is \u0394T_K = T2 – T1 = 210 K – 240 K = -30 K. The question asks for the change *without sign*, so the magnitude of the change is 30 K. Since \u0394T_K = \u0394T_C, the change in Celsius is \u0394T_C = 30\u00b0C. The corresponding change in Fahrenheit is \u0394T_F = (9\/5) * \u0394T_C = (9\/5) * 30 = 9 * 6 = 54\u00b0F.
