Question

Which law of thermodynamics states

that energy can neither be created nor

destroyed; energy can only be

transferred or changed from one form to

another?

A. The zeroth law of thermodynamics

B. The first law of thermodynamics

C. The second law of thermodynamics

D. The third law of thermodynamics​

Answer 1

Ans. B

Sol. The first law of thermodynamics

states that energy can neither be created

nor destroyed; energy can only be

transferred or changed from one form to

another. It is also called law of

conversation energy. For example,

turning on a light would seem to produce

energy; however, it is electrical energy

that is converted

⭐The Laws of Thermodynamics ⭐

=> The Zeroth Law of Thermodynamics states that "Two systems in thermal equilibrium with a third system separately, are in thermal equilibrium with each other..."

=> The First Law of Thermodynamics states that "Energy can neither be created nor be destroyed, but can only be converted from one form to another, and can only be transferred from one system to another..."

=> The Second Law of Thermodynamics states that "The entropy of the universe always increases in every spontaneous natural process..."

According to Kelvin-Planck's statement, "It is impossible to devise a cyclically operating device, whose sole effect is the absorption of energy in the form of heat from a single from reservoir, and the performance of an equivalent amount of work..."

According to Claussius' statement, "In no process can the heat transfer from a colder to a warmer object take place without some other change, connected therewith, occurring at the same time..."

=> The Third Law of Thermodynamics states that "The entropy of a perfectly crystalline substance approaches zero, as its temperature approaches the absolute zero..."
