- Disciplinary Core Ideas
- PS3.A Temperature is a measure of the average kinetic energy of particles of matter. The relationship between the temperature and the total energy of a system depends on the types, states, and amounts of matter present.
- NRC Framework
- Thermal energy is the random motion of particles (whether vibrations in solid matter or molecules or free motion in a gas)...
