A resistance thermometer which measures temperature by measuring the change in resistance of a conductor, is made of platinum and has a resistance of 50.0 ohms at 20.0 degrees Celsius.

a) When the device is immersed in a vessel containing melting indium, its resistance increases to 76.8 ohms. From this information, find the melting point of indium.

b) The indium is heated further until it reaches a temperature of 235 degrees Celsius. What is the new current in the platinum to the current IMP at the melting point?
