Question

What happens to the pressure in a sealed container if the amount of a gas in the container

increases?
Pressure stays the same.
Pressure increases and then quickly decreases
Pressure increases.
Pressure decreases.

Answer 1

i believe the pressure would increase because there would be less room for the gas to move, making it more difficult and resulting in added pressure

Answer 2

Pressure increases.

Step-by-step explanation:

The pressure in a gas is the result of the collision of the particles or molecules that form the gas with the walls of the container.

In this example we know that the area of the walls of the container is going to remain constant since is a sealed container, so if the amount of gas increases the particles will also increase, and the pressure will not be the same as when there were fewer particles, so with more particles in the container we can conclude that there will be more particle-wall collisions, and the pressure will increase.
