Question

question 2
how does the number of particles affect the pressure?

• increasing the number of particles increases the pressure.
• increasing the number of particles does not change the pressure.
• increasing the number of particles decreases the pressure.

Explanation:

According to the kinetic theory of gases, when the number of particles (moles of gas, for example) increases in a fixed volume and temperature, the frequency of particle collisions with the container walls increases. More collisions mean a greater force per unit area, which is pressure. So increasing the number of particles leads to an increase in pressure.

Answer:

A. Increasing the number of particles increases the pressure.
