Question

"The mass and energy both are conserved in an isolated system", is the statement of ______.

Options

• second law of thermodynamics

• third law of thermodynamics

• modified first law of thermodynamics

• first law of thermodynamics

Answer 1

"The mass and energy both are conserved in an isolated system", is the statement of modified first law of thermodynamics.

Explanation:

The modified first law of thermodynamics states that "In an isolated system, both mass and energy are conserved." According to this law, if a particular amount of one type of energy is created, an equal amount of another type of energy is consumed, resulting in constant total energy in the universe.
