1. The problem statement, all variables and given/known data 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? 2. Relevant equations Tf = (9/5)*Tc+32 where Tc is temperature in celsius and Tf is temperature in fahrenheit 3. 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?
