An ideal monatomic gas expands adiabatically from 0.500 m to 1.69 m. If the initial pressure and temperature are 1.20 x 105 Pa and 340 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 (d) the work done on the gas (in J) Need Help? Read It Watch It
