Question

The boiling point of a liquid can be raised by

• A. Increasing pressure
• B. Decreasing pressure
• C. Increasing the heat supply
• D. Increasing the quantity of the liquid

Answer 1

The correct option is A Increasing pressure

When water heats up the molecules move faster and faster and move farther apart, eventually becoming steam. When the pressure on the water is increased, the molecules are more tightly held. This helps keep them from moving apart so it requires more heat to get them to "break free" and move apart. So, the higher the water pressure the higher the boiling point.
