What is the primary reason why gases are highly compressible?
What is the primary reason why gases are highly compressible?
- The molecules are far apart and have weak intermolecular forces. (correct)
- The molecules are in a fixed position and have no kinetic energy.
- The molecules have high kinetic energy and are constantly moving.
- The molecules are closely packed and have strong intermolecular forces.
Why do gases assume the shape and volume of their container?
Why do gases assume the shape and volume of their container?
- Because the molecules are stationary and have no motion.
- Because the molecules are in constant random motion and evenly distribute themselves. (correct)
- Because the molecules are repelled by the container walls.
- Because the molecules are attracted to the container walls.
