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.

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...

Please Help!!!!
13. Carbon dioxide (typically called dry ice when it?s in solid form) transitions between its solid phase and its gas phase at a temperature of -78.5 degree C. Suppose we have 3.12 kg of dry ice at -125 degree C. flow much heat must be added to transform all of the dry ice into gas with an equilibrium temperature of -78.5 degree C? The latent heat of sublimation of dry ice is 5.72 x 10^5 J/kg and the...

You have a block of ice at a temperature of -100°C. This block of ice is made from 180g H2O. The block of ice will be heated continually until it becomes super-heated steam at a temperature of 200°C Cice = 2.03 J/g-K ΔHfus=6.01 kJ/mol Cwater = 4.18 J/g-K Csteam = 1.84 J/g-K ΔHvap=40.67 kJ/mol What is the enthalpy change raising the temperature of 180 g of ice at −100 °C to 0°C? What is the enthalpy change upon melting 180...

Assume that you have 40000 molecules of carbon dioxide in a box at a temperature of 300 K. Also, imagine if the speed distribution of the molecules is governed by the following function N(v) = Ave(-Mv^2/2RT) instead of a Boltzmann distribution N(v) = Av2e(-Mv^2/2RT) Normalize this function to solve for A. Also, solve for the vrms of the carbon dioxide gas. [Use .044 kg/mol for the molar mass of carbon dioxide] Group of answer choices a) A = .706, Vrms = 348.25...

F: How much energy is needed to raise the temperature of the water from 20.0°C to 100.0°C? Part E: Suppose the block in part D is made of steel(iron, c = 449 J/kg-K) and has a mass of 0.500 kg and has an initial temperature of 300.0°C. The block is placed into the insulated beaker that holds 50.0 ml of water at 20.0°C. If the metal block were to cool to 100.0°C, how much energy would be transferred to the...
