We can divide pure substances into two classes: elements and compounds. Pure substances that cannot be broken down into simpler substances by chemical changes are called elements.

How does kinetic energy transferred between atoms and molecules?

On a microscopic scale conduction occurs as rapidly moving or vibrating atoms and molecules interact with neighboring particles transferring some of their kinetic energy. Heat is transferred by conduction when adjacent atoms vibrate against one another or as electrons move from one atom to another.

What is thermal energy exchange between objects of different temperatures?

Two objects with different temperatures can exchange energy, if they are in thermal contact. The energy exchanged between objects because they are in thermal contact is called heat.
