Suppose you are hiking down the Grand Canyon. At the top, the temperature early in the morning is a cool 1.25 "C. By late afternoon, the temperature at the bottom of the canyon has warmed to a sweltering 34.6 "C. What is the difference between the higher and lower temperatures in (a) Fahrenheit degrees and (b) kelvins?A copperconstantan thermocouple generates a voltage of 4.75 x 10'3 volts when the temperature of the hot junction is 110 \"C and the reference junction is kept at 0 \"C. If the voltage is proportional to the difference in temperature between the junctions, what is the temperature in degrees Celsius of the hot junction when the voltage is 1.53 x 10'3 volts
