A closed gas system initially has a pressure and volume of 0.403 atm and 7103 mL with the temperature unknown. If the same closed system has values of 2.41 atm, 2509 ml, and
81.00°C, what was the initial temperature?

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.
