A40 g sample of dry ice (COz(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. A Without knowing the work involved, we cannot calculate the internal energy change

. 0-175 J +175 J +350 J -350 J
