The most likely phase of the substance is 'liquid'.
Explicação
## Step 1The problem describes a substance that occupies half of an open container and has atoms that are closely packed but can still slide past each other. This description is indicative of a phase of matter.## Step 2The first part of the description, "The substance occupies one half of an open container", suggests that the substance is not a gas. Gases tend to fill their entire container, not just half of it.## Step 3The second part of the description, "The atoms of the substance are closely packed but are still able to slide past each other", is a key characteristic of liquids. In a liquid, the atoms or molecules are closely packed, but they are not as tightly bound as in a solid. This allows them to slide past each other, which is not the case in a solid.## Step 4The description does not suggest that the substance is a solid and gas mixture. The ability to slide past each other is a characteristic of liquids, not solids.
