A 1400 cm expandable container holds an ideal gas that is initially at 50.0 .C and 1.04x10 Pa. The gas undergoes a process that causes it to expand to 1800 cm at a pressure of 1,13x10 Pa. "] Before the gas expands, what is its absolute temperature? [K] b) Before the gas expands, how many moles of gas are there? [ mol ] After the gas expands, how many molecules of gas are there? [# of molecules] d) After the gas expands, what is its absolute temperature? [K] e] If the gas did the same expansion, but keeps its initial pressure, what would the gas's final temperature be? ["C]
