A gas goes from state A to state B and increases its volume as shown in the figure above.  (4 pts) Calculate the work done as it expands from State A to State B along the direct path AB. (2 pts) If 200 kJ of heat is added as it goes along the direct path AB, what is the change in internal energy of the gas?

A sample of gas occupies a volume of 0.010 m³ at a pressure of 101325 Pa and a temperature of 298 K.(3 pts) Using the ideal gas law, calculate the number of moles of gas in the sample. (3 pts) The gas is compressed to a volume of 0.005 m³ at the same temperature. Assuming the number of moles remains constant and the gas behaves ideally, calculate the new pressure of the gas.

The firm of Le & Lysius was conducting the audit of Coomes Molding Corporation for the fiscal ended October 31. Michelle Le, the partner in charge of the audit, decides that monetary unit sampling (MUS) is the appropriate sampling technique to use in order to audit Coomes’s inventory account. The balance in the inventory at October 31 was $4,250,000. Michelle has established the following: risk of incorrect acceptance = 5% (i.e., the desired confidence level of 95%), tolerable misstatement = $212,500, and expected misstatement = $63,750. a) Calculate the sample size and sampling interval. (1 points) b) Hon Zhu, staff accountant, performed the audit procedures listed in the inventory audit program for each sample item. Using the sample size computed in part a, calculate the upper limit on misstatement based on the following misstatements. What should Hon conclude about Coomes’s inventory account?
