Does a solid forms when the average energy of a substance's particles decreases then increases?
Decreases.
What causes the particles of a substance to lose thermal energy?
The particles in a substance lose thermal energy as the temperature decreases, because the particles are moving and vibrating less.
Molecules in a substance slow down when a substance is?
Molecules in a substance slow down when a substance is cooled. Temperature is the measure of average kinetic energy of particles. Kinetic energy is the energy of motion. So when temperature decreases, the average kinetic energy decreases, so the energy of motion decreases, and the molecule slows down.
Has thermal energy been transfered into or out of a substance if the average kinetic energy changes?
Temperature is a measure of the average KE of the PARTICLES of a substance. So if the temperature changes, ave KE changes, thus thermal energy will have been transferred.
Explain the changes that have to take place for a substance to go from solid to liquid to gas?
Since particles are tightly packed together solid melts when energy increases. Example: ice SInce particles are fairly close together liquid evaporates/boils when energy increases. Example: Boiling Water. SInce particles have little attraction in gas. It condenses when energy decreases. Liquid solidifies when energy decreases.

What Explain what happens to the average kinetic energy, thermal energy, and temperature of a substance when the particles in the substance slow down.?
The particles in a substance slow down when the average kinetic energy of the particles decreases. As the average kinetic energy decreases, the internal energy decreases, and so the thermal energy decreases. As the thermal energy of the substance decreases, the temperature decreases.

What happes to particles when a substance gains energy and changes state?
particals
How is the kinetic energy of the particles that make up a substance different after it changes?
If you mean by heating it... When you heat a substance, the thermal energy of its particles increases. This means that the particles will move around faster as they have a higher kinetic energy.
Does potential energy increases or decreases when gas changes to liquid?
The potential energy of a substance decreases when it changes into a liquid. This is because it's losing the heat energy it had when in gas form to become liquid.
How does adding energy to matter by heating it affect the energy of its particles?
Adding heat will do one of the following, or both: * The temperature of the substance increases. The individual particles move faster; their kinetic energy increases. * The substance changes its state (for example, when ice melts, it changes from solid to liquid). The potential energy of the particles increases.
What happenes to particles as the temperature decreases?
As the temperature decreases, kinetic energy decreases, and particles slow down.

What happens to substance during changes between gas to liquid?
The particles of the substance gain kinetic energy as they absorb heat energy. Eventually there is enough kinetic energy for the particles to escape the liquid phase, forming the gas phase.
