As the bottle is carried from 14,000 feet to 9,000 feet to 1,000 feet, it becomes compressed. what would happen if you took a normal-shaped bottle, sealed it at 1,000 feet, and then carried it up to 14,000 feet?

It would expand.

Explanation:

The bottle sealed at 14,000 feet is compressed as height above sea level decrease because the atmospheric pressure increases at the same time. Then, a bottle sealed at 1,000 feet would expand as height above sea level increase because of the atmospheric pressure decrease.

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
