Needs Answer -
1. Vinegar is an ingredient commonly used by chefs. Scientists also use it as well, although they call it acetic acid. When vinegar is in
its liquid or solid (frozen) states, it has a fixed volume. But when vinegar is in its gas state, it takes up the entire volume of whatever
container it is in. This is why you can smell an open bottle of vinegar the minute you walk into a kitchen, even though you cannot actually
see the gas particles!
Which statement best explains why the volume of vinegar gas is changeable as opposed to the fixed volume of its solid and liquid states?
O A. Gas particles are always at a higher pressure than solids and liquids.
O B. Gas particles are always at a higher temperature than solids and liquids.
оо
C. Gas particles are spaced far apart and can move freely.
O D. Gas particles stay close together but can move around each other.
2. A chemist finds several unlabeled bottles, each containing a clear liquid. Unsure if the liquids in the bottles are different or not, she
decides that she should perform a quick investigation of the liquids' properties.
