1. To answer this question, we need to understand the concept of particle arrangement in different substances. In solids (like a block of wood or an ice cube), the particles are tightly packed together and cannot be drawn closer to occupy a smaller volume. In fruit juice, the particles are also close together but can be rearranged or squeezed to occupy a smaller volume. However, the correct answer to this question is c. air inside the syringe because gases, like air, have particles that are widely spaced and can be compressed or drawn closer together to occupy a smaller volume.

2. In order to determine which phenomenon does NOT involve the application of gas pressure, we need to understand the concept of gas pressure and apply it to each scenario. Gas pressure is the force exerted by gas particles on the walls of their container. A. burning fuels involves the combustion of gases, which produces gas pressure. B. falling leaves are not directly related to gas pressure. C. vulcanizing tire involves the application of pressure to ensure proper bonding and curing of the tire. D. rising hot air balloons involve the expansion of gas inside the balloon, creating gas pressure. Therefore, the correct answer is b. falling leaves.

3. In order to explain the blown out tire during a long summer drive, we need to consider the concept of gas behavior. When a tire explodes, it is due to an increase in pressure inside the tire. In this case, the correct answer is c. The mass of the gases inside the tire increases causing a blown up tire. This is because as the temperature rises during a long drive, the air inside the tire heats up and expands, resulting in an increase in mass and pressure, ultimately causing the tire to blow out.

4. To prove that gases have negligible mass, we need to design an experiment that demonstrates this concept. The correct answer is a. put a balloon in a digital balance before and after you fill it with air. By measuring the mass of the balloon before and after filling it with air, any change in mass would be due to the mass of the gas inside the balloon. Since gases have very low density compared to solids or liquids, the change in mass would be negligible, providing evidence that gases have negligible mass.

5. When the volume of a gas decreases at constant pressure and temperature, its density increases. This is because density is defined as the mass of a substance divided by its volume. As the volume decreases, the same amount of gas particles are packed into a smaller space, resulting in an increase in density. Therefore, the correct answer is b. increases.

6. The law that explains the mechanism of a gas compressor is a. Boyle's Law. Boyle's Law states that at a constant temperature, the volume of a gas is inversely proportional to its pressure. In the case of a gas compressor, the volume of the gas is decreased, causing an increase in pressure.

7. The gas law that best explains the explosion of a heated aerosol container is c. Combined Gas Law. The Combined Gas Law combines Boyle's Law, Charles' Law, and Gay-Lussac's Law to describe the relationship between the pressure, volume, and temperature of a gas. In the case of a heated aerosol container, the temperature of the gas inside the container increases, causing an increase in pressure. If the pressure becomes too high, it can cause the container to explode.

8. The gas law that explains the relationship among volume, pressure, temperature, and the number of moles of gases is d. Ideal Gas Law. The Ideal Gas Law combines Boyle's Law, Charles' Law, and Gay-Lussac's Law with the number of moles of a gas to describe the relationship between pressure, volume, temperature, and the number of moles of a gas in a system. The equation for the Ideal Gas Law is PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature.

9. Gas molecules exhibit translational movement. Translational movement refers to the motion of gas molecules as they move from one place to another in a straight line. Gas molecules have high kinetic energy, allowing them to move freely and randomly throughout a container.

10. As the temperature increases, the average kinetic energy of gas molecules also increases. The kinetic energy of gas molecules is directly proportional to the temperature. When the temperature increases, the gas molecules move faster and have higher kinetic energy. Therefore, the correct answer is b. as the temperature decreases, the average kinetic energy of gas molecules increases.

11. As the temperature increases, the gas pressure also increases if the amount and volume of the gas are kept constant. This relationship is described by Charles' Law. Charles' Law states that at constant pressure, the volume of a gas is directly proportional to its temperature. As the temperature increases, the gas molecules move faster and collide more frequently with the walls of the container, resulting in an increase in pressure. Therefore, the correct answer is c. the gas pressure increases.
