Under constant pressure P = 1 atm an ideal gas of 1.5 mol undergoes cooling from 120°C to 30.0°C, and CV,m = 3/2R. Please calculate q, w, AU, and AH (all units are J). Please enter all four answers using scientific notation (E notation) with three significant figures, such as 2.30E4 (=23000). If the answer is negative, please do not forget the negative sign. If answer is zero, please just enter O without decimal. (1) q= -2.81E3 (2) W= -1.12E3 (3) AU= -1.68E3 (4) AH= -2.81E3
