1. A sample of carbon monoxide (CO) gas has a volume of 7.31L at a pressure of 735 mm Hg and a temperature of 45°C. Determine the following for this gas sample: a. Pressure in milliliters of mercury at T = 357°C and V=13.5L b. Temperature in degrees Celsius at P = 1275 mm Hg and V = 0.800L c. Volume in liters at T = 45°C and P = 325 mm Hg d. Pressure in atmospheres at T = 325°C and V = 2.31L

Which concept best accounts for the fact that gases can escape through a pinhole faster at higher temperatures? Select one: O a. A gas is composed of molecules whose size is much smaller than the distances between them. O b. Gas molecules move randomly--at various speeds and in every possible direction. O c. Except when molecules collide, forces of attraction and repulsion between them are negligible. d. When collision occur, they are elastic. Oe. The average kinetic energy of gas molecules is proportional to the absolute temperature. Frombois III (Log out) G Search or type URL % 5 6 & 7 || ☆ 00- 8 ( ( Finish attempt ...

Urgent please!:) 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?   A.  The compressed N2 gas has a higher density than the compressed H2 gas.   B.  Both cylinders contain approximately the same number of molecules.   C.  Molecules of H2 move faster on average than molecules of N2.   D.  The pressure of the N2 gas is higher than the pressure of the H2 gas.   E.  None of the other statements is correct.
