Which of the following statements is supported by the first law of thermodynamics?
A The energy inside any system is equal to the energy outside.
B The total amount of energy in the universe is steadily decreasing.
C Energy can never enter a closed system, nor can it leave a closed system
D The total energy in a closed system is a conserved quantity.

Respuesta :

Answer:

D The total energy in a closed system is a conserved quantity.

Explanation:

As we know by first law of thermodynamics that heat given to the system is equal to the Sum of change in internal energy of the system and Work done by the system

So we have

[tex]Q = \Delta U + W[/tex]

so we can say that heat given to the system is the form of energy which is converted into other forms and this total energy is conserved

So correct answer will be

D The total energy in a closed system is a conserved quantity.
