To determine the phase of the substance based on the volume provided for Containers 1 and 2, we can analyze the information given.
- In Container 1, the substance has a volume of 5 cubic meters.
- In Container 2, the volume increases to 10 cubic meters.
If the substance can occupy varying volumes like this, it suggests that it behaves like a fluid, which typically means it is either a liquid or a gas.
However, since the volume can change significantly upon transfer (from 5 cubic meters to 10 cubic meters), this indicates that the substance is likely in a gaseous state. Gases expand to fill the volume of their containers.
Based on the options given:
- "solid or liquid" would not be correct as solids and liquids have fixed volumes.
- "liquid or gas" could be valid, but the change in volume strongly favors the gas phase.
- "liquid" is not the best choice because the change in volume suggests it is not behaving like a liquid.
- "gas" is the most accurate answer considering the substantial increase in volume.
Therefore, the substance is most accurately described as being in the gas phase.
