Structures and Properties of Matter

The smallest part of an element that still retains the properties of that element

• compound

• atom

• matter

• electron

The energy transferred between objects that are at different temperatures; flows from the substance with the higher temperature to the substance at a lower temperature; caused by friction due to collisions of particles

• heat

• temperature

• sound energy

• chemical energy
