Explain using particle theory of matter, how a liquid changes to a gas.
Answers
✔✔The particles need energy to overcome the attractions between them.
✔✔ As the liquid gets warmer more particles have sufficient energy to escape from the liquid.
✔✔Eventually even particles in the middle of the liquid form bubbles of gas in the liquid.
✔✔. At this point the liquid is boiling and turning to gas.
Answer:
All matter is composed of many tiny particles in constant motion. In a liquid, the particles are close together but can FLOW past each other due to sufficient kinetic energy. Thus, it is a FLUID. In a gas, the particles are far apart and have much kinetic energy. They are moving quickly.
When the particles of a liquid acquire enough kinetic energy to be far apart from each other, then the liquid has turned to a gas. This is generally accomplished by heating the liquid, but most liquids will generally evaporate over time due to the distribution of particles with a few always having enough ke to leave the surface of the liquid and become a gas.
