water that vanish out of an open container explain the term in kinetic molecular theory of matter

Answer 1

In the kinetic molecular theory of matter, it is proposed that matter is made up of tiny particles in constant motion. In the case of water evaporating out of an open container, the water molecules are moving at various speeds due to their kinetic energy. When the container is open, some water molecules near the surface gain enough energy to break away from the liquid phase and enter the gas phase. This process is known as evaporation. The rate of evaporation is dependent on factors such as temperature, pressure, and surface area of the liquid. So in the context of the kinetic molecular theory of matter, the disappearing water molecules are simply particles exhibiting kinetic energy and transitioning between different phases.
