The molar heat capacity cp, m of so2(g) is described by the following equation over the range 300 k < t < 1700 k: cp, mr = 3.093+6.967×10−3tk −45.81×10−7t2k2+1.035×10−9t3k3 in this equation, t is the absolute temperature in kelvin. the ratios tn/kn ensure that cp, m has the correct dimension. 1.60 moles of so2(g) is heated from 27.0 ∘c to 1.10×103 ∘c at a constant pressure of 1 bar. explain the sign of w.
