The true statements about gas particles are:
b) There are no forces of attraction between gas particles.
c) The collisions between particles are perfectly elastic.
d) Because gas particles spread out to fill their container, the particles of a gas are much smaller than the distances between them.
e) Gas particles are in constant, random motion.
h) The faster the particles of the gas moves, the more frequently and forcefully they will strike the walls of the container.
To answer this question, we need to evaluate each statement and determine if it is true or false.
a) There are forces of attraction between gas particles.
This statement is false. Gas particles have little to no forces of attraction between them. In the gas phase, the particles are far apart and move freely, leading to negligible intermolecular forces.
b) There are no forces of attraction between gas particles.
This statement is true. As mentioned earlier, gas particles have minimal forces of attraction between them.
c) The collisions between particles are perfectly elastic.
This statement is generally true. In an ideal scenario, gas particles collide with each other and with the container walls in perfectly elastic collisions. This means that no energy is lost during the collision, and the total kinetic energy remains constant.
d) Because gas particles spread out to fill their container, the particles of a gas are much smaller than the distances between them.
This statement is true. Gas particles are small compared to the distance between them. They occupy a larger space when they fill their container.
e) Gas particles are in constant, random motion.
This statement is true. Gas particles are in constant motion, moving randomly in all directions. This motion is a result of their kinetic energy.
f) The slower the particles of a gas move, the more frequently and forcefully they will strike the walls of the container.
This statement is false. The speed of gas particles does not affect the frequency or forcefulness of their collisions with the container walls. The frequency and force of collisions depend on factors such as pressure, temperature, and volume.
g) The collisions between gas particles are inelastic.
This statement is false. Gas particles exhibit elastic collisions, as explained in statement c.
h) The faster the particles of the gas moves, the more frequently and forcefully they will strike the walls of the container.
This statement is true. The faster gas particles move, the more frequently and forcefully they collide with the container walls. This is because their higher kinetic energy leads to more frequent and energetic collisions.
In conclusion, the true statements about gas particles are:
- There are no forces of attraction between gas particles.
- Gas particles are in constant, random motion.
- Because gas particles spread out to fill their container, the particles of a gas are much smaller than the distances between them.
- The faster the particles of the gas moves, the more frequently and forcefully they will strike the walls of the container.
