1. Form a hypothesis: As altitude increases, the air pressure decreases. How do you think the lower pressure will affect the following? (Circle your answers.) A. Freezing point: Increase, Stay the same or Decrease B. Melting point Increase Stay the same Decrease C. Boiling point: Increase Stay the same Decrease​

Respuesta :

Answer:

A. Freezing point: Increase.

B. Melting point: Decrease

C. Boiling point:  Decrease​

Explanation:

  • As we go up in higher altitudes the air becomes on and less dense, hence the decrease in the water vapor content at such altitude leads to a decrease of boiling point.
  • Thus the air above is cool and much colder than at the ground surface. The vapor pressure is temperature-dependent and thus melting point will also decrease.
