While taking photographs in death valley on a day when the temperature is 52.0°c, bill hiker finds that a certain voltage applied to a tungsten 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 no change occurs in the wire's shape and size.

The air in an automobile tire with a volume of 2.60 ft3 is at 70°f and 21 psig. determine the amount of air that must be added to raise the pressure to the recommended value of 30 psig. assume the atmospheric pressure to be 14.6 psia and the temperature and the volume to remain constant. the gas constant of air is ru = 53.34ft⋅lbflbm⋅r(1 psia144 lbf/ft2) = 0.3704 psia⋅ft3lbm⋅r the amount of air that must be added to raise the pressure is lbm
