Swedish physicist Johannes Rydberg
Explanation:
b. Pressure
Explanation:
Pressure is a physical effect that can change the boiling point of a substance.
Pressure is the force per unit area on a body.
- A substance will boil when the vapor pressure of its heated molecules is greater than the atmospheric pressure.
- The higher the atmospheric pressure, the higher the temperature and energy required to boil a substance.
- At high altitude, the atmospheric pressure is low and the boiling point of substances is lower.
