1. Thermal Energy
and Matter

2. 1. Differentiate between heat and temperature2
GOALS
1. Differentiate between heat and temperature
2. Explain common examples, such as ice in a soda, to show the direction of energy flow.

3. Heat Heat is a form of energy
Total heat in an object = total KE of motion in its atoms.
Heat is the transfer of KE from one material to another.

4. Heat
Total heat depends on: how fast the molecules are moving and the # of molecules present.

5. Heat All matter has heat energy, even ice!
There can be a lot of heat in a substance even if the temperature is low: Ex. The ocean
Heat can flow from one object to another

6. Temperature
Temperature is the measurement of the avg. KE of the molecules in a material.
Measured in Celsius, Kelvin, or Fahrenheit.

7. Becoming Familiar with Celsius
1. Freezing = ___________ 2. Boiling = ___________ 3. Room temp. = ___________ 4. Body temp. = ___________
0oC
100oC
25oC
37oC

8. Heat flows
from WARMER to
COLDER!
