Your instructor gives you a 100 g of dry ice (solid carbon dioxide) at -100 °C. Through the course of an experiment, you end up with 100 g of gaseous carbon dioxide at 0 °C. Answer the following questions based on this data. Assume that no heat is lost to the outside environment during the experiment. The specific heats for solid and gaseous carbon dioxide are 0.296 and 0.203 cal/g-°C respectively. Remember, carbon dioxide sublimes from solid to gas at...

Dry ice is frozen carbon dioxide. If you have 1.8 kg of dry ice, what volume will it occupy if you heat it enough to turn it into a gas at a temperature of 20degreeC? Assume P_atm = 1-013X 10^5 Pa and R = 8.315 J/mol . K.

To practice Problem-Solving Strategy 19.1 The First Law of Thermodynamics. A 2.60 mol sample of carbon dioxide undergoes a two-step process. First, at a constant volume, the gas behaves ideally as it is cooled from 21.0 degree C to -78.5 degree C where it reaches a pressure of 1 atm. Second, at -78.5 degree C and a constant pressure of 1 atm the gas undergoes a phase change to dry ice. What is the change in internal energy of carbon...

Air flows over a solid slab of frozen carbon dioxide formed in dry ice with an exposed cross- sectional area of 1.0x109 m². The carbon dioxide sublimes into the 2.0 m/s flowing stream at a total of mass flux rate is 2.29x107 mol/s and partial pressure is 4.7410Pa. The air is at ambient conditions of 293 K and 1.01310% Pa pressure. At this ambient condition, the diffusivity of carbon dioxide in air is 1.5x10-6 m²/s. At ambient conditions (293 K...
