Question

A bottle containing air only is sealed with a cork. When the bottle is heated to a high enough temperature, the cork eventually pops out of the bottle.

Why did the cork pop?

Responses

When gas particles gain energy, they move faster and exert greater pressure.
When gas particles gain energy, they move faster and exert greater pressure.

An increase in temperature causes gas particles to chemically combine with one another.

An increase in temperature causes gas particles to chemically combine with the glass of the bottle.

Answer 1

The answer is
When gas particles gain energy, they move faster and exert greater pressure

Answer 2

When gas particles gain energy, they move faster and exert greater pressure.

Step-by-step explanation:

Heating a gas increases the average kinetic energy of its particles.

As gas particles gain energy, they move more rapidly and collide with the walls of the container (or the cork in this case) with increased force.

The increased frequency and force of these collisions result in higher pressure inside the bottle.

Eventually, if the pressure becomes too great, the cork may pop out of the bottle due to the increased force exerted by the gas particles.
