Question

how can you increase the speed of particles in an airtight container? (1 point)
increase the size of the container
increase the temperature of the container
decrease the temperature of the container

Explanation:

According to the kinetic - molecular theory, the average kinetic energy of gas particles is directly proportional to the temperature. Increasing the temperature increases the kinetic energy, which in turn increases the speed of the particles. Changing the size of the container does not directly affect the speed of the particles in terms of temperature - related kinetic energy.

Answer:

Increase the temperature of the container
