Question

michael has a substance that he puts in container 1. the substance has a volume of 5 cubic meters. he then puts the substance in container 2, and it now has a volume of 10 cubic meters. in which phase(s) is the substance?
○ solid or liquid
○ liquid or gas
○ liquid
○ gas

Explanation:

To determine the phase of the substance, we analyze the volume change with container change:

• Solids have a definite volume and shape, so their volume doesn't change with the container.
• Liquids have a definite volume but take the shape of the container, so their volume also doesn't change with the container.
• Gases have neither a definite volume nor shape; they expand to fill the container, so their volume changes with the container's volume.

Here, the substance's volume changes from 5 to 10 cubic meters when moved to a different container, indicating it expands to fill the container, characteristic of a gas.

Answer:

D. gas
