Question 4 5 pts Gas storage containers are sometimes designed to store the gas at a low temperature. This allows more gas to be stored at a lower pressure, and therefore more safely. Consider a rigid (constant volume) gas container that can safely store ny moles of gas at a higher temperature Th = 309 K and pressure PH = 5.79 x 10^6 Pa. Calculate the number of moles of gas, nį, that this container can hold at a lower...
