1. The problem statement, all variables and given/known data
At 30ąC, the resistance of a segment of gold wire is 79 ohms*. When the wire is placed in a liquid bath, the resistance increases to 165 *ohms. The temperature coefficient is 0.0034/C at 20 degrees Celcius. What is the temperature of the bath? An swer in units of C. 2. Relevant equations Resistance = R(initial)[1+ alpha (T(final)  T(initial)] 3. The attempt at a solution 165 = 79 * ( 1 + .0034 * (T_final  30) ) T_final = 350.1787 I'm submitting this and it's saying I'm wrong. Is the homework service in error?
