Answer:
Gas particles can move like solids and liquids along with translational motion.
Gas collisions are elastic.
Explanation:
The gases take the form of the container that contains them, are compressible, expandable and diffuse in the medium that contains them.
Elastic collisions occur against the container that contains them in the case of gases, without loss of kinetic energy in said interaction.
The atoms and molecules of gases are in constant motion, unlike liquids and solids.
Answer:
The correct answer is:
Explanation:
Gases mix faster than solids or liquids: In gases, unlike solids and liquids, the attractive forces are almost non-existent, so the particles are very far apart from each other and move quickly and in any direction. So, since the gas particles are freely arranged and have more empty spaces, they mix easily. So, the statement is correct.
Gas particles can move like solids and liquids along with translational motion: Previously it was mentioned that gases mix faster than solids or liquids. The gases have their very separated particles moving chaotically in all directions through a translational movement. In contrast to solids, the particles are joined by very large attractive forces, so they remain fixed in place; they only vibrate next to each other. So, the statement isn't correct.
Gas collisions are elastic: The molecules move in a straight line at high speed and only interact when they collide. Crashes between particles and with the vessel walls are considered perfectly elastic, conserving translational kinetic energy. Expressed in other words, gas molecules possess kinetic energy. In the movement, the gas molecules collide elastically with each other and with the walls of the container that contains them in a perfectly random way, that is, in each shock the energy is delivered from one particle to another, and therefore they can continue in constant motion The frequency of collisions with the walls of the vessel explains the pressure exerted by the gases. So, the statement is correct.
Gases with larger molecular weights diffuse slower than gases with lower molecular weights : Diffusion is the process of expansion through space by gas. Graham's Law is a gas law that relates the gas velocity to its molar masses. This law states that the diffusion of gases is inversely proportional to the square root of their molar masses.
[tex]\frac{v1}{v2} =[\frac{M2}{M1} ]^{\frac{1}{2} }[/tex]
So, the rate of effusion of gas with lower molecule mass will be more than the rate of effusion of gas with higher molecular mass.
Finally, the statement is correct.
Gases with larger molecular weights diffuse faster than gases with lower molecular weights: This statement is not correct. It can be explained by the Graham Law mentioned above.
