Temperature is a measure of the amount of heat stored in a substance... true or false?

temperature is the measure of the kinetic energy of the molecules of a substance





more kinetic energy more heatTemperature is a measure of the amount of heat stored in a substance... true or false?
False.





It is the movement of atoms in the the material. The hotter the temperature, the faster the atoms are moving - smashing into each other and ';off the sides'; so to speak.





As the temperature falls, the atoms are moving slower and slower.





As you can see from this explanation, temperature simply can't go down forever. Eventually, the atoms come to a complete standstill. This is at the temperature -273 degrees C or ';absolute Zero'; or ';Kelvin';. There is no temperature colder than this. Even in deepest outer space, it is a degree or two above this.
