Question

The energy required to raise the temperature of an iron ball by 1 K is 500 JK-1. Calculate the amount of energy required to raise its temperature by 20 K.​

Answer 1

The energy required to raise the temperature of an iron ball by 1 K is 500 JK-1. Calculate the amount of energy required to raise its temperature by 20 K.

The energy required to raise the temperature of an iron ball by 1 K is 500 JK-1 .

Heat capacity c = Q/∆T

Q = C×∆T

Hence , C = 5000 J K-¹

∆ T = 20 K
