Air pressure decreases as elevation increases. Identify how the boiling point of water on top of a mountain would be different from its boiling point at sea level. Draw two models to show how the particle motion and the state of water on the mountain top and at sea level would change if you kept adding thermal energy to water that was already at 100°C. Label your models to show what happens to the temperature as the energy is added.
