Two identical pressurized-gas cylinders contain two different gases: N2 and H2. The cylinders have equal masses (with the gases inside) and are at the same temperature, 25 °C. Which one of the following statements about these systems is correct? O A. None of the other statements is correct. O B. The pressure of the N2 gas is higher than the pressure of the H2 gas. O C. The compressed N2 gas has a higher density than the compressed H2 gas. O D. Both cylinders contain approximately the same number of molecules. O E. Molecules of H2 move faster on average than molecules of N2.
