Which of the following internal macroscopic states of the body changes when a bullet is fired from a gun?
-
A.
Heat energy
-
B.
Temperature
-
C.
Kinetic energy
-
D.
Chemical energy
Correct Answer:
C. Kinetic energy
Explanation:
When a bullet is fired from a gun, its internal chemical energy, stored within the gunpowder, undergoes a rapid transformation. As the gunpowder ignites, this chemical potential energy is converted into kinetic energy and thermal energy, propelling the bullet forward. Since the internal macroscopic state of a system includes its stored energy forms, the reduction in chemical energy signifies a change in the body's internal state. Therefore, the internal chemical energy is the macroscopic state that changes during this process.
