A gas is at a temperature above its boiling point. The gas is then cooled so that it becomes a liquid at a temperature below its boiling point.
Which row correctly compares the gas with the liquid?
| Average distance between the particles | Average speed of the particles | |
|---|---|---|
| A | greater in the gas | greater in the gas |
| B | greater in the gas | smaller in the gas |
| C | smaller in the gas | greater in the gas |
| D | smaller in the gas | smaller in the gas |
greater in the gas | greater in the gas
greater in the gas | smaller in the gas
smaller in the gas | greater in the gas
smaller in the gas | smaller in the gas
