Two metal blocks that have slightly different temperatures are placed next to one another. after five minutes, they both have lower but equal temperatures. according to the law of conservation of energy, what  most likelyhappened? energy was created inside the blocks. energy was destroyed inside the blocks. energy was absorbed into the blocks from outside the system. energy was transferred from the warmer block to the cooler block.

Energy was transferred from the warmer block to the cooler block

Explanation:

None of the above.

Explanation:

If the blocks were an isolated system, the cooler block would warm up.

However, both blocks cooled down, so they both must have transferred heat energy to their surroundings.

A and B are wrong. According to the Law of Conservation of Energy, energy can neither be destroyed nor created.

C is wrong. If energy was absorbed into the blocks from outside the system, the cooler block would have warmed up.

D is partially correct. Both blocks must be hotter than their surroundings. If the cooler block gets colder, it must have transferred heat energy to the surroundings. The warmer block also lost energy to the surroundings. However, it could have transferred some energy to the cooler block, which then lost it to the surroundings. The final temperature of each block is the temperature of the surroundings.

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
