Apply the kinetic molecular theory to predict the outcome regarding the gas shown at right under each of the conditions below by filling in "increases" or "decreases" in the space provided. 1. If temperature is increased, the number of collisions per second. 2. If volume is increased, the number of collisions per second. 3. If the number of particles is increased, the number of collisions per second.

Answer: The correct answer for

1) Increases

2) Decreases

3) Increases

Explanation: Kinetic molecular theory explained about the behavior of the gas particles.

1) The number of collisions of the particles is directly proportional to the temperature because as the temperature increases, the kinetic energy of the particles increases and therefore, the number of collisions will increase.

2) The volume is increased, the number of collisions per second will decrease because as the volume increases, the distance between the particles will increases and hence, the collisions between them will decrease.

3) The number of particles is increased, the number of collisions per second will increase because the distance between the particles will decrease and hence, the collisions between them will increase.
