Q. 11
Explain how three states of matter arise due to the variation in the characteristics of the particles.
Answer
There is variation in the characteristics of particles of solid, liquid and gas. But matter can change its state; i.e., from solid to liquid and liquid to gaseous and vice-versa.
From solid to liquid:
When we supply heat to a solid, with the increase in temperature, the kinetic energy of particles in a solid also increases. The particles start vibrating at high speed about their fixed position. At a certain temperature, a moment arises when the energy supplied by heat overcomes the intermolecular force of attraction between the particles. The particles then break free and leave their fixed position and start moving freely. At this stage, the solid starts melting and gets converted into a liquid.
From liquid to gas:
When we supply heat to a liquid, with the increase in temperature, the kinetic energy of particles in a liquid also increases. The particles start moving faster. At a certain temperature, a point is reached when the energy supplied by heat overcomes the intermolecular force of attraction between the particles, and the particles move randomly at a greater speed in any direction. At this stage, the liquid starts boiling and gets converted into gas.
Answer:
matter means any thing which has mass and ocuppies the space is known as matter matter are three type they are solid,liquid,gasses
