Question

(a) internal human body temperature is often stated to be normal at 98.6°f. what is this temperature on the celsius and kelvin scales? (b) gallium boils at 2205°c. what is the corresponding temperature in the fahrenheit and kelvin scales? (c) the boiling point of liquid nitrogen is 77.0 k. what is the corresponding temperature in the fahrenheit and celsius scales?

Answer 1

(a)The formula for converting Fahrenheit to Celsius is (Temp°F-32) x 5/9. (98.6-32) x 5/9 = 37°C. Celsius to Kelvin is a matter of adding 273.15 to the Celsius. 37 + 273.15 = 310.15°K (b)Celsius to Fahrenheit is Temp°C x 9/5 +32. 2205 °C x 1.8 + 32 = 4001°F 2205 °C + 273.15 =2478.15°K (c) first convert to Celsius. 77 °K - 273.15 = -196.15 °C -196.15 x 1.8 + 32 = -321.07°F
