Question

Energy, while always being conserved, becomes useful, i.e. it cannot be used to performed mechanical work. This is called

• A. degradation of energy
• B. decomposition of energy
• C. chemical energy
• D. none of the above

Answer 1

Answer: (A)

degradation of energy

When we try to perform work whole conserved energy cannot convert into work some amount of energy goes to surrounding in the form of heat energy this is called as second law of thermodynamics. Released energy to surrounding is called as degradation of energy.
