An ideal monatomic gas expands adiabatically from 0.530 m³ to 1.72 m³. If the initial pressure and temperature are 1.30 x 105 Pa and 355 K, respectively, find the number of moles in the gas, the final gas pressure, the final gas temperature, and the work done on the gas. HINT (a) the number of moles in the gas (Enter your answer to at least three significant figures.) mol (b) the final gas pressure (Enter your answer in Pa, to at least three significant figures.) Pa (c) the final gas temperature (in K) K

Ideal diatomic gas (y = 1.40 ) has initial temperature of 181 K , initial volume of 0.163 m3, and initial pressure of 33.0 kPa . (a) The gas expands at constant pressure until its volume reaches 0.338 m³. Find the work done on the gas during this process. W, = kJ (b) After that, the gas is compressed isothermally until its pressure becomes 85.0 kPa . Find the final volume of the gas. V2 = m n3 (c) Find the final temperature of the gas. T2 K

An ideal monatomic gas expands adiabatically from 0.560 m³ to 1.66 m³. If the initial pressure and temperature are 1.60 x 105 Pa and 335 K, respectively, find the number of moles in the gas, the final gas pressure, the final gas temperature, and the work done on the gas. HINT (a) the number of moles in the gas (Enter your answer to at least three significant figures.) 32.17 ✔ mol (b) the final gas pressure (Enter your answer in Pa, to at least three significant figures.) 26156.9 Pa (c) the final gas temperature (in K) 162.34 (d) the work done on the gas (in J) X J

The temperature at state A is 20.0ºC, that is 293 K. During the last test, you have found the temperature at state D is 73.0 K and n = 164 moles for this monatomic ideal gas. What is the work done by the gas for process D to B, in MJ (MegaJoules)? 1.0 atm = 1.00 × 105 Pa.
