What is the change in the internal energy, in Btu/lbm, of air as its temperature changes from 100 to 200°F? Is there any difference if the temperature were to change from 0 to 100°F?The constant-volume specific heat of air at room temperature is cv = 0.171 Btu/lbm·R. Consider the variation of specific heat with temperature. cv = 0.1725 Btu/lbm·R at 150°F and cv = 0.1712 Btu/lbm·R at 50°F.
