The boiling point of water is 212∘F. In degrees Celsius, how much heat do I have to add to boil water that is already 194∘F? Use the formula C = 59(F − 32), where C represents the temperature in degrees Celsius and F represents the temperature in degrees Fahrenheit.

You need to add 10 °C of heat.

Step-by-step explanation:

To find the quantity of heat in Celsius first we need to convert the units:

212 °F to °C (boiling point):

   (1)

194 °F to °C:

   (2)

Now we can find the quantity of heat that must be added by substrating equation (2) from (1):

Therefore, you need to add 10 °C of heat to boil water that is 90 °C.    

I hope it helps you!

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
