Temperature

The temperature may be defined as the heat strength or heat level of a matter. Temperature alone does not give the quantity of heat in a substance but it is a suggestion of the degree of heat, or how hot the body is. The molecular theory of heat states that temperature is a sign of the velocity of movement of the molecule. It is important not to use the words heat and temperature carelessly. 

Temperature measures the speed of motion of one molecule, while heat is the speed of motion of the molecule PLUS the figure of molecules (weight) so exaggerated. Example: A little copper dish heated to 1340 F. does not contain as much heat as 5 pounds of copper heated to 300 F. but it is warmer. That is, its heat level is advanced or its strength of heat is better, but it does not contain as much high temperature.
