All molecules vibrate. The amount depends on how hot or cold the object is. The vibrations are movement.
Thermal energy is defined as the movement of molecules within an object.
Matter is composed of molecules. These molecules move around. The movement stops only when a body of matter reaches absolute zero (about -253 degrees Celsius). The higher the temperature, the more movement. With movement increase, the distance between molecules increases, so the volume gets bigger.
Conduction occurs when two object at different temperatures are in contact with each other. Heat flows from the warmer to the cooler object until they are both at the same temperature. Conduction is the movement of heat through a substance by the collision of molecules. At the place where the two object touch, the faster-moving molecules of the warmer object collide with the slower moving molecules of the cooler object. As they collide, the faster molecules give up some of their energy to the slower molecules. The slower molecules gain more thermal energy and collide with other molecules in the cooler object. This process continues until heat energy from the warmer object spreads throughout the cooler object.
The heat energy of a substance is determined by how active its atoms and molecules are. A hot object is one whose atoms and molecules are excited and show rapid movement. A cooler object's molecules and atoms will be less excited and show less movement. When these guys are in the excited state, they take up a lot of space because they're moving around so fast. When the atoms and molecules settle down, or cool down, they take up less space...
Temperature. When atoms or molecules move faster, the temperature is higher. At Absolute Zero, all movement would stop.
It means the object has NO ACCELERATION.

Thermal energy is defined as the movement of molecules within an object.
Temperature IS the average speed of movement of the particles molecules that make up an object. The more heat you add to an object, the faster the molecules move vibrate. There are devices thermometers that indirectly measure this speed, and thus report the temperature.
They don't necessarily move to another place. However, the movement of the molecules INSIDE the object speeds up. (:
In chemistry, heat is the measurement of how fast molecules vibrate back and fourth as they travel through space and time. In other word, the faster the molecules vibrate, the hotter the object gets. The slower the molecules vibrate, the cooler the object gets.
