calculate the internal energy and enthalpy changes resulting if air changes from an initial state of 5°c and 10 bar, where its molar volume is 2.312 × 10−3 m3 ·mol−1 , to a final state of 60°c and 1 bar. assume also that air remains a gas for which pv/t is constant and that cv = 20.785 and cp = 29.100 j·mol−1 ·k−1 .

A(t)=(t−k)(t−3)(t−6)(t+3) is a polynomial function of tt, where kk is a constant. given that a(2)=0a(2)=0, what is the absolute value of the product of the zeros of aa?
