A 2.8 g sample of pure metal requires 10.1 J of energy to change its temperature from 21°C to 36°C. What is this metal? Substance Specific Heat Gold 0.129 J/g °C Silver 0.237 J/g °C Copper 0.385 J/g °C Water 4.18 J/g °C​

Silver 0.237 J/g °C

Explanation:

We know that the heat required to raise the temperature of a given mass of a substance through a given temperature rise is given by;

H = mcθ

Where;

m = mass of the body

c = specific heat capacity of the body

θ = temperature rise

10.1 J = 2.8 g * c * (36°C - 21°C)

c = 10.1 J /  2.8 g * (36°C - 21°C)

c = 0.24 J/g °C

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.
