Classwork p. 8 Solid Liquid Gas Melting Boiling Phase Changes are flat because…

Classwork p. 8 Phase changes are flat because there is no temperature change. Kinetic energy (the energy of movement) increases with temperature. Potential energy (energy from particle configuration) increases during melting and boiling.
