Solids, liquids and gases — practice question

When the temperature is X, raising the pressure from $1\,\text{atm}$ to $2\,\text{atm}$ leaves the volumes of the hexane and pentane samples unchanged. At temperature X, pentane molecules are able to move freely, but hexane molecules are arranged in fixed positions. What are the states of hexane and pentane at temperature X?

  • Ahexane: liquid; pentane: solid
  • Bhexane: liquid; pentane: gas
  • Chexane: solid; pentane: liquid
  • Dhexane: solid; pentane: gas
