Ms. Dunbar is teaching her class about states of matter. She put two beakers on a lab table. The beakers were labeled beaker X
and beaker Y. Each beaker contained the same liquid substance. She heated beaker X and she decreased the pressure in
beaker Y. The students in the class then observed the beakers. What are possible states of matter that could have been contained
in each beaker at the end of the demonstration?
OA.
Both beakers could have contained gases.
OB. Beaker X could have contained a gas, and beaker Y could have contained a solid.
OC. Both beakers could have contained solids.
OD.
Beaker X could have contained a solid, and beaker Y could have contained a gas.
