Question

Conservation of mass is valid for
a. Both fixed and moving control volumes
b. Fixed control volumes
c. Arbitrary control volumes
d. None of the above​

Answer 1

the correct option is D.

BECAUSE IT USE FOR CHEMICAL REACTION

Answer 2

Conservation of mass is valid for d. none of the above

Explanation:

• The law of conservation of mass explains that the mass is neither created nor destroyed in chemical reaction.
• Thus, this conservation of mass is valid for mass involved in any chemical reactions.
• This law specifies the reaction only and not to the volume changes.
• The volume get changed, it should affect the mass of the compound also.
• So, the conservation of mass is not valid for any fixed or moving control volumes.
• Hence, the correct answer is d. None of the above.
