Which of the following statements is true tor real gases? Choose all that apply. As molecules increase in size, deviations from ideal behavior become more apparent at relatively high pressures. Attractive forces between molecules cause a decrease in pressure compared to the ideal gas. The volume occupied by the molecules can cause a decrease in pressure compared to the ideal gas. As molecules increase in size. deviations from ideal behavior become more apparent at relatively low pressures.

Part A) Which of the following statements is true for ideal gases, but is not always true for real gases? Choose all that apply. Molecules are in constant random motion. Pressure is caused by molecule-wall collisions. The size of the molecules is unimportant compared to the distances between them. The volume occupied by the molecules is negligible compared to the volume of the container. Part B) Which of the following statements is true for real gases? Choose all that apply....

Which one of the following statements is not correct? a. An increase in temperature causes an increase in gas pressure because the average force of molecules colliding with the walls of the container increases. b. An increase in temperature causes an increase in gas pressure because the frequency of molecules colliding with the walls of the container increases. c. Real gases deviate from ideal gases because of the finite size of the molecules and the attractive and repulsive interactions between...

h of the following statements is NOT true? London dispersion forces are present in all substances but are the only significant intermolecular forces in nonpolar substances. ) The density of the liquid state of a substance is greater than the density of its gaseous state. The thermal energy in a liquid allows the atoms within molecules to completely overcome the attractions between them so they flow. Most liquids can be converted to a gas by reducing pressure and/or heating. The...

Which of the following is true about a 0.200 mol sample of nitrogen gas and a 0.200 mol sample of argon gas that are at 1.20 atm and an initial temperature 55.0°C when the temperature changes to 400 K? Assume constant volume for the container under both of these temperature conditions. The density of both gases will increase. There will be more collisions between the gas molecules and the pressure in the container will decrease. None of these choices is...

Decide which of the following statements are true and which are false. True Real gas molecules have a volume and exert attractive forces on one another. False As temperature increases, the average kinetic energy of a sample of gas molecules decreases. False In order for two separate 1.0 L samples of O2(g) and H2(g) to have the same average velocity, the O2(g) sample must be at a higher temperature than the H2(g) sample. False At constant temperature, the lighter the...
