A gaseous air fuel mixture in a sealed car engine cylinder has an initial volume of To prepare for ignition of the fuel, a piston moves within the cylinder, reducing the volume of the air fuel mixture to Assuming ideal behavior, what is the new pressure of the air fuel mixture? About 0. About At Assuming ideal behavior, if the temperature of the gas was raised to Two sealed, rigid 5.
Also shown are the results of transferring the entire contents of container 1 to container 2. No gases escape during the transfer. Assuming ideal behavior, which statement is correct regarding the total pressure of the gases after they are combined? The total pressure of the gases in the mixture is the sum of the initial pressures of oxygen gas and nitrogen gas because pressure only depends on the total amount of gas when volume and temperature are held constant.
The total pressure of the gases in the mixture is lower than the sum of the initial pressures of oxygen and nitrogen because some of the energy of the particles will be lost due to an increase in the number of collisions. The total pressure of the gases in the mixture is higher than the sum of the initial pressures of oxygen and nitrogen because of the intermolecular forces that develop between oxygen and nitrogen molecules.
The total pressure of the gases in the mixture cannot be determined because the actual value of the temperature is not given. The diagrams above use arrows to represent the speed of a gas particle. Which of the diagrams best represents the speed of the particles of a gas at a fixed temperature, and why? The two gas samples represented in the graph above are at the same temperature.
Which of the following statements about the gases is correct? The diagram above shows the distribution of speeds for a sample of O2 g. Which of the following graphs shows the distribution of speeds for the same sample at a higher temperature dashed line? Equimolar samples of CH 4 g and C 2 H 6 g are in identical containers at the same temperature. The C 2 H 6 g deviates much more from ideal behavior than the CH 4 g does. Which of the following best helps explain this deviation?
C 2 H 6 molecules have a larger, more polarizable electron cloud than CH 4 molecules do. C 2 H 6 molecules have more hydrogen bonding than CH 4 molecules do.
The C 2 H 6 molecules have a greater average kinetic energy than the CH 4 molecules have. The C 2 H 6 molecules have a greater average speed than the CH 4 molecules have. The gases CO 2 g and NH 3 g can be liquefied at 20 o C by compressing them to sufficiently high pressures. A student claims that NH 3 g can be liquefied at a lower pressure than CO 2 g can be liquefied.
Which of the following is the best justification for this claim? CO 2 is a nonpolar molecule that has no significant intermolecular forces, whereas NH 3 has strong London dispersion intermolecular forces.H22a turbo build
Both CO 2 and NH 3 are nonpolar molecules that have only London dispersion intermolecular forces, but the larger electron cloud of CO 2 molecules causes it to have stronger intermolecular forces. CO 2 is a nonpolar molecule that has London dispersion intermolecular forces that are weaker than the dipole-dipole and London dispersion forces between the polar NH 3 molecules.
The graph above shows how a particular real gas deviates from ideal behavior at very high pressures. Based on this information, which of the following is most likely the gas and gives the reason based on kinetic molecular theory? A balloon filled with 0. What is the volume of the balloon at this depth?Matter, as taught in class, is anything that has weight and occupies space.
Matter exists in three different states, which can either be as a gas, liquid, or solid. The differences in these states can be identified by checking their density.

Calculate the number of moles of oxygen. If the gas is compressed to 1. As the volume increases, the particles have more space to move and collide less with the wallscausing pressure to decrease. As the volume increases, the particles have more space to move and collide less with the wallscausing pressure to increase.

Chlorofluorocarbon Quizzes.Each container has a pinhole opening. Which of the gases, He g or Ne gwill escape faster through the pinhole and why?
He g will escape faster because the He g atoms are moving at a higher average speed than the Ne g atoms. Ne g will escape faster because the Ne g atoms have a higher average kinetic energy than the He g atoms. Both gases will escape at the same rate because the atoms of both gases have the same average kinetic energy. If the temperature is held constant, what is the total pressure of the gases in the tank?
A rigid metal tank contains oxygen gas. Which of the following applies to the gas in the tank when additional oxygen is added at constant temperature? A sample of an ideal gas is cooled from Which of the following values for the gas will decrease? A sealed vessel contains 0.Alberto
The total pressure of the gas mixture is 5. The partial pressure of the argon is. A vessel contains Ar g at a high pressure. Which of the following statements best helps to explain why the measured pressure is significantly greater than the pressure calculated using the ideal gas law?
The attractive forces among Ar atoms cause them to collide with the walls of the container with less force. The combined volume of the Ar atoms is too large to be negligible compared with the total volume of the container. Ar g deviates more from ideal behavior at extremely high pressures than Ne g does. Which of the following is one reason for this difference? Ar atoms have more valence electrons than Ne atoms have, so Ar atoms have greater interparticle forces. At constant temperature, the behavior of a sample of a real gas more closely approximates that of an ideal gas as its volume is increased because the.
