Answer

Brief Explanations:

Gas molecules have high energy and move randomly. Also, in a gas, most of the volume is intermolecular empty space (unlike solids where molecules are closely - packed).

  • Option A: Molecules in a gas move randomly, not uniformly. So, A is incorrect.
  • Option B: Gas molecules are high - energy, move randomly, and most of the volume is intermolecular space. This is correct.
  • Option C: Gas molecules are high - energy, not low - energy, and the volume is mostly empty space (not closely - packed molecules). So, C is incorrect.
  • Option D: Gas molecules are high - energy (not low - energy), move randomly (not uniformly), and the volume is mostly empty space (not closely - packed molecules). So, D is incorrect.

Answer:

B. collection of randomly moving high energy molecules with majority of the volume coming from intermolecular empty space
