Answer:
what to do in this question
The liquid to solid process using the particle theory is as below
- The process that involve change of liquid to solid is known as Freezing
- It involve change from a high energy state to lower energy
- The constant temperature at which a liquid change to solid by giving out heat energy is called freezing point of the liquid
- when liquid are cooled the thermal energy of particles decrease.
- The cohesive forces between the particles strengthen to such extent that particles can have relative motion with each other and they occupy the fixed position, thus liquid is converted to solid
