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.

its first and third is your answer i did the qustion the fourth isnt right

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
