When the mass of the sun is larger, earth moves around the sun at a faster or slower pace. when the mass of the sun is smaller, earth moves around the sun at a faster or slower pace. when earth is closer to the sun, its orbit becomes faster or slower. when earth is farther to the sun, its orbit becomes faster or slower.

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
