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...

QUESTION 16 15. Gas 1 and gas 2 are in containers of equal volume (V1=V2). If T1 = T2, m1 < m2, and n1 = n2, then what is true about the pressure, P, in the two containers? Note: T is the temperature in Kelvins, m is the molecular mass of the gas, n is the quantity of matter in moles. O A Pq< P2 B. pq > P2 C.P - P2, always D.P - P2, at low temperatures only...
