At 31.8°C, the resistance of a segment of gold wire is113.4Ω.

When the wire is placed in a liquid bath, the resistancedecreases to 96.8 Ω.

What is the temperature of the bath?

The temperature coefficient for gold is 0.0034 (°C)−1 at20°C.

Answer in units of °C.

What do we do when the initial temperature is not 20°C?
