During freezing, a substance? -loses chemical energy -loses thermal energy -gains thermal energy -gains chemical energy

The process of melting a crystalline solid can be

reversed if the liquid is cooled. The change from the liquid state

to the solid state is called freezing. As the liquid cools, it loses

thermal energy. As a result, its particles slow down and come

closer together. Attractive forces begin to trap particles and the

crystals of a solid begin to form.

"The total kinetic energy of all the particles in a sample of

matter is called thermal energy. Thermal energy, an extensive

property, depends on the number of particles in a substance as

well as the amount of energy each particle has. If either the

number of particles or the amount of energy in each particle

changes, the thermal energy of the sample changes. With identically sized

samples, the warmer substance has a greater thermal energy."
