Item EG055004: The thermal energy of an object depends on the speed and type of molecules that make up the object.
The thermal energy of an object depends on which of the following?
- Both the speed and the type of molecules that make up the object
- The speed of the molecules that make up the object but not the type of molecules
- The type of molecules that make up the object but not the speed of the molecules
- Neither the speed nor the type of molecules that make up the object

- 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)...
