1. INTERNAL
ENERGY AND
TEMPERATURE

2. Let’s start with temperature.

3. Compare their temperatures.
They have the same temperature,
both 0 C.

4. Compare their temperatures.
They have the same temperature,
both 100 C.

5. Compare their temperatures.
The boiling water is hotter at 100 C,
compared to the ice cube at 0 C.

6. Then, how about internal
energy?

7. Compare their internal
energies.
The iceberg has more internal energy
because it has more mass.

8. Compare their internal
energies.
The boiling water in the bigger basin has more
internal energy because it has more mass.

9. Compare their internal
energies.
Boiling water has more internal energy
because of its higher temperature.

10. Compare their internal
energies.
Although boiling water has higher temperature,
the iceberg has greater internal energy
because it has so much more mass.

11. Tying it up together:
Heat transfers from an area of higher
temperature to an area of lower
temperature.
 The object that the heat transferred to
often has its internal energy and
temperature increased.
 The object that the heat transferred
from often has its internal energy and
temperature decreased.
