An ideal gas is compressed isothermally from 7.73 L to 2.93 L, at a starting pressure of 7.24 atm and temperature of 90.85 C. 1. How many moles of gas are present? Submit Answer Tries 0/99 2. What is the final pressure (in atm) of the gas? Submit Answer Tries 0/99 3. If the compression is carried out reversibly and isothermally, how much work (in )) is done on the system? Submit Answer Tries 0/99 4. What is the heat flow in part 3? Remember that for an ideal gas, AU = 0 for isothermal processes. Submit Answer Tries 0/99
