If the number of gas molecules in an enclosed container is increased while the volume and temperature remain constant, what happens to the pressure exerted by the gas?
Correct Answer
Pressure increases
Explanation
Increasing the number of gas molecules means there are more particles available to collide with the container walls. With more frequent collisions, the total force exerted on the walls increases, leading to a higher pressure.
