| sample | change in volume when squeezed |
|---|---|
| A | large |
| B | almost none |
| C | almost none |
Table 1.1 compares how easily three samples, A, B and C, can be compressed.
Which sample is a gas?
Answer Details
The correct answer is A. A gas is easily compressed because of the large spaces between its particles, so the sample whose volume changes by a large amount when squeezed, sample A, is the gas. Samples B and C change volume by almost nothing, meaning their particles are already close together (a liquid or solid), so neither is the gas.
