I will evaluate my understanding of energy transfer as it is increasing the energy content of one system while decreasing the energy content of the other system by the same amount

5. KEY VOCAB 02: WORDS 5, 6

7. 1.
The Law of Conservation of Energy states that energy can neither be created nor destroyed, but instead is transferred between a system and its surroundings. 

8. This energy transfer often occurs in the form of heat flow.2.
This energy transfer often occurs in the form of heat flow.

9. 3.
Heat, or the movement of thermal energy from a warmer substance to a cooler substance, flows between a system and its surroundings, and can be quantified by measuring the change in temperature of each system.

10. 4.
As one of the fundamental principles in nature, the Law of Conservation of Energy has many different expressions in different fields.

11. For instance, the Bernoulli Equation is the corresponding expression in flowing fluid.

12. Thermal energy is transferred from the hand (warm) to the ice cube (cold), melting the ice.
When an ice cube is placed on an outstretched palm, the body heat transfers to the ice cube, the temperature of the ice cube increases, and the ice begins to melt.

13. 5.
As body heat transfers from the hand to the cube, nerves of the body sense the heat transfer and signal the brain, where the sensation is interpreted as cold. In fact, the words cold and warm do not have meaning in science because they are relative terms that just describe varying amounts of heat. Real cold in science means without heat, or absolute zero, which is numerically defined as 0o on the Kelvin scale and o on the Celsius scale.

14. 6.
Celsius is used as the SI unit for measurement of temperature. The two other temperature scales are Fahrenheit and Kelvin.

15. 7.
Cold only exists at or below absolute zero. As temperatures above absolute zero increase, the relative amount of heat also increases.
