At an atmospheric pressure of 1.01×105Pa, carbon dioxide (CO2) sublimes at a temperature of -78.5∘C. The heat of sublimation is 5.71×105J/kg. You let heat flow into 6.0 kg of solid CO2 (volume 4.0×10−3m3) at atmospheric pressure and a constant -78.5∘C until it has completely sublimed to gas at -78.5∘C.The CO2 gas occupies a volume of 3.4 m3. A) For this process, calculate how much heat flows into the CO2. B) For this process, calculate how much work the CO2 does...

A cylinder contains 0.250 mol of carbon dioxide (CO2) gas at a temperature of 27.0∘C. The cylinder is provided with a frictionless piston, which maintains a constant pressure of 1.00 atm on the gas. The gas is heated until its temperature increases to 127.0∘C. Assume that the CO2 may be treated as an ideal gas. How much work W is done by the gas in this process? What is the change in internal energy ΔU of the gas? How much...
