Temperature is an intensive property, while heat is an
extensive property. An intensive property means that the
amount of substance present will not change the specific
trait. For example, the boiling point of water is 100
degrees. One liter of water boils at 100 degrees the same
as 15 liters of water boils at 100 degrees.
An extensive property is one that does depend on amount
present. An example is that the amount of heat produced by
one liter of boiling water will differ from the amount of
heat produced by 15 liters of boiling water.
A good comparison of heat and temperature is shown with
fireworks sparklers. The sparks that come off of the
sparkler are ejected particles of metal, and temperatures
of these sparks can reach up to 3000 degrees C. However,
these sparks will not burn you if they land on you, even
though the temperature is extremely high. Why? The sparks
do not have enough mass and cannot contain enough heat.
Though the sparks have high temperature, the amount of heat
(thermal energy) they contain is very small.
