A 20 g sample of dry ice (CO₂(s)) is placed in a glass flask and a stopper is tightly placed in the flask opening to seal it. Since the dry ice is much colder than its surroundings, 350 J of energy transfers into the flask in the form of heat. If you can, determine the change in internal energy of the CO2 in the flask. Without knowing the work involved, we cannot calculate the internal energy change. O-175 J +175 J +350 J -350 J
