Question

Use the particle theory to explain,liquid to soild process

Answer 1

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
