A500 ml glass of liquid n-pentane at 283 k is removed from a refrigerator that is located outside on a very hot day in phoenix. the n-pentane slowly equilibrates to the ambient temperature, which is 110 °f. the process occurs at 1 bar. calculate the entropy change of the n-pentane, δsn-c5, the entropy change of the surroundings, δssurr, and the entropy change of the universe, δsuniv. neglect the heat capacity of the container. the normal boiling point for n-pentane is 309.2 k, liquid density is 626 kg/m3 , and heat of vaporization can be taken as 25.79 kj/mol. assume constant cp values ca be used, with a liquid cp value of 169 j/mol-k, and a vapor cp value of 126 j/mol-k.
