The resistance of the tungsten wire is 3.000 w at 20degc, Ask an Expert

Academics

A tungsten wire is used to determine the melting point of indium. The resistance of the tungsten wire is 3.000 W at 20°C and increases to 4.850 W as the indium starts to melt. atungsten = 4.50 ´ 10-3 (°C)-1. What is the melting temperature of indium?
