Question

Experiment with different amounts of gas particles in the simulation. What happens to the gas pressure when the number of particles is reduced at constant temperature and volume?


The pressure decreases.


The pressure increases.


The pressure stays the same.


The gas particles stop moving.

Answer 1

When the number of gas particles in a simulation is reduced while keeping the temperature and volume constant, the pressure decreases. This is because pressure is directly related to the number of collisions between gas particles and the walls of the container. With fewer particles, there are fewer collisions occurring, leading to a decrease in pressure. Therefore, the correct answer is:

**The pressure decreases.**
