While taking photographs in Death Valley on a day when the temperature is 50.0°C, Bill Hiker finds that a certain voltage applied to a platinum wire produces a current of 1.000 A. Bill then travels to Antarctica and applies the same voltage to the same wire. What current does he register there if the temperature is -88.0°C? Assume that no change occurs in the wire's shape and size.

Bill is one weird guy. I've taken photographs in Death Valley, but it was only about 40C and I didn't bring my platinum wire and ammeter with me.
Go look up the temperature dependence of resistance in platinum
