Question

question 1
select all that are correct.
the spacing between particles of a gas...
□ results in the particles not interacting with each other through intermolecular attractions
□ results in it smelling bad
□ is large relative to the size of the particles
□ allows the gas to be compressed
□ results in gases having low densities
□ means that it is mostly empty space

Explanation:

• "results in the particles not interacting...": Gas particles have weak intermolecular forces, and large spacing means interactions are negligible (not "not interacting" but very weak, but this option is often considered correct in basic models as interactions are minimal due to spacing).
• "results in it smelling bad": Smell depends on gas type, not particle spacing. Incorrect.
• "is large relative to the size of the particles": A key property of gas particles—spacing >> particle size. Correct.
• "allows the gas to be compressed": Large spacing means particles can be pushed closer. Correct.
• "results in gases having low densities": Low density as mass is spread over large volume (due to spacing). Correct.
• "means that it is mostly empty space": With large spacing, most of the gas volume is empty. Correct.

Answer:

• is large relative to the size of the particles
• allows the gas to be compressed
• results in gases having low densities
• means that it is mostly empty space
• results in the particles not interacting with each other through intermolecular attractions (note: technically intermolecular forces exist but are weak, but this is a common simplification in basic gas models)
