Select one:a. When a gas is in a larger volume, the molecules have more space and bump into the walls of the flask more, thereby exerting a greater pressure. b. When a gas is in a smaller volume, the molecules are more confined and bump into the walls of the flask more, thereby exerting a greater pressure. c. The volume of the gas does not account for the changes in the pressure. d. When a gas is in a smaller volume, the molecules have more space in the flask, thereby exerting a smaller pressure.How did your data collected in Experiment 1 with propane gas compare to the data you collected in Experiment 2 using butane?Select one:a. The pressure values from propane gas were lower than for butane gas. b. The two experiments produced very different data. c. Both experiments produced the same data. d. The pressure values from propane gas were higher than for butane gas.What can you conclude based on the data that you collected from Experiments 1 and 2?Select one:a. Gases behave similarly with respect to pressure and volume regardless of the identity of the gas. b. Gases behave similarly with respect to pressure but not with respect to volume regardless of the identity of the gas. c. Gases behave differently with respect to pressure and volume regardless of the identity of the gas. d. Gases behave differently with respect to pressure and volume depending on the identity of the gas.Suppose you conducted a similar experiment using helium gas.

The amount and temperature will increase.Deep water fish such as the ones in the figure below are highly sought after for home aquariums. However, these fish are hard to transport to the surface safely. Why do you think that is?Select one:a. As the water pressure decreases, there is not enough oxygen for the fish in the water. b. As the water pressure increases, the air in their swim bladders compresses until they burst. c. As the water pressure decreases, the air in their swim bladders compresses until they burst. d. As the water pressure decreases, the air in their swim bladders expands until they burst.
