Question

You can convert temperature given in degrees Celsius to a Fahrenheit temperature by using the expression 9x / 5+ 32 , where x is the celsius temperature .
a) Water freezes when the temperature is 0 degree C . At what Fahrenheit temperature does water freeze ?



b)Water boils at 100 degree Celsius . At what temperature does water boil in degrees Fahrenheit ?


c) The temperature of some water is 15 degree Celsius . What is the Fahrenheit temperature ?

Answer 1

The formula given in the question for conversion of temperature is

F = 9x/5 + 32
a. When temperature = 0 degrees centigrade, then
F = (9 * 0)/5 + 32
   = 0 + 32
   = 32 degree Fahrenheit

b when temperature of boiling water = 100 degree Celsius, then
F = (9 * 100)/ 5 + 32
   = 900/5 + 32
   = 212 degree Fahrenheit

c. When temperature of water is 15 degree Celsius, then
F = (9 * 15)/5 + 32
   = 27 + 32
   = 59 degree Fahrenheit
