Joe noted that the temperature in his aquarium dropped overnight. he concluded that thermal energy moved from the aquarium to the air around it. does this validate or invalidate the law of conservation of energy? a. invalidate, because energy should not leave a closed systemb. invalidate, because the amount of energy should stay constant c. validate, because an aquarium is an open system that loses and gains energy d. validate, because the amount of energy lost was replaced by matter

Answer choices are:

A. Invalidate, because energy should not leave a closed system

B. Invalidate, because the amount of energy should stay constant

C. Validate, because an aquarium is an open system that loses and gains energy

D. Validate, because the amount of energy lost was replaced by matter.

The correct answer choice is:

C. Validate, because an aquarium is an open system that loses and gains energy.

Explanation:

As we know that, the law of conservation of energy is that the total amount of energy of an isolated system prevails to be constant, it is said to be maintained or conserved over time. This law means that energy can neither be created nor be destroyed; rather, it can only be converted or transferred from one form to another.

the answer is c.) there is a warm front in region a and a stationary front in region b.
