i feel rather stupid posting this, but i can't seem to figure it out:
increase a sample by 43.8 degrees celsius. if the sample is already 62.7 degrees fahrenheit, what is the temperature in degrees fahrenheit when the desired temperature increase has been achieved?
Tf = (9/5)*Tc+32 where Tc is temperature in celsius and Tf is temperature in fahrenheit
The Attempt at a Solution
convert 43.8 celsius to fahrenheit:
Tf = (9/5)(43.8+32) = 110.84 fahr.
sum initial temp and converted temp:
Tfinal = 110.84 + 62.7 = 173.54 fahr.
i know that the answer is NOT 173.54 fahr because the "temperature change does not depend on the freezing point of water." what am i doing wrong?
