The specific heat capacity of copper metal is 0.385 J/g · K. How much energy is required to heat 168 g of copper from ―12.2 °C to +25.6 °C?

Interpretation Introduction

Interpretation:

Energy required to heat a definite mass of copper at different temperature has to be calculated.

Concept Introduction:

Heat energy required to raise the temperature of 1g of substance by 1k.Energy gained or lost can be calculated using the below equation.

q=C×m×ΔT

Where,

q= energy gained or lost for a given mass of substance (m),

C =specific heat capacity

ΔT= change in temperature

Explanation

Given

C=0.385J/g.K

Mass of copper =168g

Tfinal=25.60C

Tinitial=-12.20C

Calculate the ΔT using, ΔT =Tinitial-Tfinal

ΔT =298
