Question

Gold has a very low specific heat capacity, just 0.13 J/goC. If a gold class ring has a mass of 4 grams and is heated from 0oC to 100oC, what is the amount of energy the gold class ring has absorbed? a 52 Joules b 0.325 Joules c 400 Joules d 3076.92 Joules

Answer 1

a 52 Joules

Step-by-step explanation:

Specific heat capacity of Au = 0.13 J/g° C

mass = 4 gram

initial temperature = 0° C

final temperature = 100° C

We are to determine the amount of energy absorbed

Using the formula:

Q = mcΔθ

Q = 4 × (0.13) J/g° C ×(100-0)

Q = 52 Joules
