A sample of bismuth undergoes a temperature change of -3.15 °C while releasing 176.2 calories of heat. The specific heat capacity of bismuth is 0.029 cal/(g-°C). What is the mass of this sample?

the answer is b & c i believe : )

i think its 5049.

i hope this !

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.
