Heat is closely related
but not the same as
temperature
Heat is a flow of
energy from one
object at a higher
temperature to an
object at a lower
temperature
If you add energy to heat, at a certain point
the energy will
go up. Then the
temperature will
no longer go up
and heat will
change the
physical
state of water.
(Steam)

Heat is always the transfer on energy from an
object of an higher temperature to a lower
temperature.
 When energy flows
from a warmer object
to a cooler object,
the thermal energy of both
of the objects changes.


When you put ice cubes in a pitcher of
lemonade this is another example of thermal
energy
Energy is transferred from the warmer
lemonade to the colder ice.
As energy is transferred the average kinetic
energy decreases.
Why?
The most common units of heat
measurement are the calorie and the joule.
 One calorie is the amount of energy needed
to raise the temperature of one gram of
water by 1 degree Celsius.
 Everyone thinks
of a calorie in terms
of food, correct?



One calorie is equal to one
kilocalorie or 1000 calories
This means that one
calorie in terms of food
contains enough energy to
raise the temperature of 1
kilogram of water by 1
degree Celsius


Each calorie in food
contains 1000 calories of
energy
They figure a calorie in
food by using a
calorimeter. They heat
the food item such as
cake.

In the
scientific
community
a joule is
used to
measure
energy



One calorie is equal to 4.18
joules
The amount of energy
required to raise the
temperature of 1 gram of a
substance by 1 degree Celsius
is specific heat
Basically each substance
absorbs a different amount of
energy required to increase
overall temperature


The larger the mass is the more kinetic energy
it will have. Therefore the larger item will have
a higher specific heat.
The temperature of larger bodies of water such
as lakes also affect the temperatures of its
shores.


During the spring/summer the lake warms
slowly which keeps the shore cool
During the fall/winter the lake cools slowly,
which keeps the shore warmer
