The kinetic energy in particles would be increasing in the following cases:
1. When an external force is applied on the particles, causing them to accelerate. As the particles gain speed, their kinetic energy increases.
2. When the particles move from a region of lower temperature to a region of higher temperature. This increase in temperature leads to an increase in the average velocity of the particles, increasing their kinetic energy.
3. When a chemical reaction occurs that releases energy, such as combustion. The released energy can increase the kinetic energy of the particles involved in the reaction.
4. When potential energy is converted into kinetic energy. For example, if a particle is in a higher position in a gravitational field and falls down, potential energy is converted into kinetic energy as the particle gains speed.
5. In a system of colliding particles, if the collisions are inelastic, some kinetic energy may be converted into other forms (such as heat, sound, or deformation). However, if the collisions are elastic, the kinetic energy of the particles remains constant.
It is important to note that these are just a few examples, and there may be other situations where the kinetic energy in particles can increase.
