Question

question 4.
what is the law of conservation of energy?
a. energy is constantly increasing in all systems.
b. energy is only conserved in closed systems.
c. energy cannot be created or destroyed, only transferred or transformed.
d. energy is a constant value in open systems.

Explanation:

The Law of Conservation of Energy states that energy cannot be created or destroyed. It can only change forms (transfer or transform). Option A is wrong as energy isn't increasing in all systems. Option B is incorrect because energy is conserved in isolated systems (a more strict type than just closed). Option D is wrong as in open systems, energy can enter or leave, so it's not a constant value.

Answer:

C. Energy cannot be created or destroyed, only transferred or transformed.
