Question

1. Show for the ideal gas constant R that the following units equivalency is true, Re8. 3 14 l/K-mol and R«В.З 14 kPa-I/K-mol (l-liters, K«absolute temperature, J"Joules, Pa«Pascal) Please show all steps clearly 2. Cakulate the volume occupied by 20 g of carbon dioxide at a pressure of 1 bar and temperature of 30°C, assuming ide al gas be havior. What is the molar volume of CO2 under these conditions? 3. An ideal gas is heated at a constant pressure of 6 bar from an initial volume of 1.0 iter and temperature of 0°C to a final temperature of 157 a. What is the final volume of the gas? b. How many moles of gas are involved? c. Calculate the work done during the change of state of the gas Consider the change of state for 10 moles of ideal gas in a closed system as shown in the figure below 4. Velume, liters The gas undergoes a change of state from point A to point B via the path shown by the two arrows. Assuming the change of state is reversible a. what temperature change does the gas undergo during the change of state from A to B? b. what is the work done in Joules during the change of state? c. is work done by the gas on the surroundings or are the surroundings doing work on the gas? (make sure you get the sign correct) 5. Consider the change of state of an ideal gas shown in the figure below Volume, liters a. what is the work done in Joules during the change of state from A to B following the path indicated by the arrow? b. what is the work done in Joules during a change of state from B to A? c. in which case is work done by the surroundings on the gas: A-to-B or B-to A?
