The correct statement about boiling is: **The boiling point of a liquid depends on atmospheric pressure.**
Here's why the other statements are inaccurate:
1. **The boiling point of acetone is higher than the boiling point of water.** - This is false. The boiling point of acetone (about 56°C) is lower than the boiling point of water (100°C).
2. **At sea level, water can boil at any temperature.** - This is false. At sea level, water boils at 100°C (212°F). The boiling point can change with altitude but not freely at different temperatures at sea level.
3. **Water boils at a higher temperature at higher altitudes.** - This is also false. Water actually boils at lower temperatures at higher altitudes due to decreased atmospheric pressure.
So, the only accurate statement is that the boiling point of a liquid depends on atmospheric pressure.
