a substance occupies one half of an open container. the atoms of the substance are closely packed but are still able to slide past each other.\nwhat is most likely the phase of the substance?\n○ gas\n○ liquid\n○ solid and gas\n○ liquid and solid
Answer
Brief Explanations:
To determine the phase, we analyze the properties:
- Gas: Atoms are far apart and fill the container, so not gas (eliminates gas - related options).
- Solid: Atoms are tightly packed and vibrate in place, can't slide past each other.
- Liquid: Atoms are closely packed (more than gas) and can slide past each other, and liquids take the shape of the container (occupying half an open container fits as liquids have a definite volume but not shape, unlike solids which have definite shape/volume and gases which fill the container). So the substance is a liquid.
Answer:
B. liquid
