Use the kinetic theory to explain why the liquid in the container has disappeared. Use drawings
The kinetic theory states that all particles in matter are constantly in motion. In the case of the liquid in the container, the particles are moving around and colliding with each other and the container walls.
When the liquid is left in an open container, the particles near the surface of the liquid have enough kinetic energy to escape the attractive forces of the other particles and evaporate into the air. This process continues until all the liquid has evaporated.
The following drawings illustrate this process:
1. Initially, the liquid is in the container.
2. Some of the liquid particles near the surface gain enough kinetic energy to escape into the air.
3. Over time, more and more particles evaporate from the liquid and escape into the surrounding space.
4. Eventually, all the liquid particles have escaped into the air, leaving the container empty.
Therefore, the disappearance of the liquid in the container can be explained by the kinetic theory, which describes the movement of particles and how they can escape from the liquid into the air through evaporation.
