Question

If the amount of a gas in a sealed container increases what happens to the pressure in the container?
-Pressure increases and then quickly decreases
-Pressure decreases
-Pressure stays the same
-Pressure increases
I don't really understand this, could someone explain please?

Answer 1

Pressure is affected by: increasing volume of fluid, heating the fluid or cooling the fluid.

If you heat a container filled with gas, what will happen? The internal pressure will increase.

The collision of the molecules of a fluid inside the surface of the container best describes what?
A: Pressure

Therefore, the answer to your question is -Pressure increases.
