According to the kinetic-molecular theory, particles of an ideal gas have the following characteristics:
d) have negligible volumes
This means that the particles of an ideal gas are considered to be point masses, which means they occupy no volume themselves. Although in reality, gas particles do have a certain volume, this volume is extremely small compared to the volume of the container in which the gas is held.
b) have zero masses
Ideal gas particles are considered to have no mass in the kinetic-molecular theory. This assumption allows for simplified calculations and analysis of gas behavior. In reality, gas particles do have mass, but in the ideal gas model, this assumption is useful for mathematical simplicity.
c) attract each other
In the kinetic-molecular theory, particles of an ideal gas are assumed to have no attractive forces between them. This means that they do not exert any attractive forces on each other while in motion. This assumption is made to simplify the analysis and calculations of gas behavior. However, in reality, gas particles can experience weak intermolecular forces, such as van der Waals forces, which may cause a small amount of attraction between the particles.
a) are motionless
This statement is incorrect according to the kinetic-molecular theory. In fact, the kinetic-molecular theory states that particles of an ideal gas are in constant motion. They move in straight lines until they collide with other particles or with the walls of the container. The motion of gas particles is random, and their velocities can vary depending on temperature.
In summary, according to the kinetic-molecular theory:
- Ideal gas particles have negligible volumes compared to the container they occupy.
- Ideal gas particles are considered to have no mass, though in reality, they do.
- Ideal gas particles do not attract each other, although in reality, there may be weak intermolecular forces between them.
- Ideal gas particles are in constant random motion.
According to the kinetic-molecular theory, particles of an ideal gas:
d) have negligible volumes.
According to the theory, the particles of an ideal gas are considered to be point masses, meaning they occupy no physical space. This assumption allows for simple calculations and analysis of gas behavior.
