Laura filled three syringes, A, B and C, with 40 cm3 of matter each. She then tried to push the plungers in. She recorded the markings the plungers were at before and after the experiment. The table below shows her findings.

Based on her findings, Laura drew two conclusions:

Conclusion 1: Syringes A and C must contain solids.

Conclusion 2: Syringe B must contain a gas.
