Question

Which statement describes how a macroscopic property of gases provides information about microscopic gas particles?A. Gases fill their container, showing that gas particles are not tied together and can move far apart.B. Gases fill their container, showing that gas particles are strongly attracted through electrostatic forces.C. Gases have a fixed volume, showing that gas particles are strongly attracted through electrostatic forces.D. Gases have a fixed volume, showing that gas particles are not tied together and can move far apart.

Answer 1

It's important to know that gases don't have a defined volume as solids do because they don't have a definite shape.

Also, gas partcles are not tied together because their intermolecular forces are weak, this enables them to travel away one from another.

Therefore, the answer is A.
