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
