Your friend comes across a good deal to purchase a gold ring. she asks you for advice and for you to test the ring. the ring has a mass of a 4.54 g. when you heat the ring with 94.8 j of energy, its temperature rises from 23.0°c to 47.5°c. would you advise your friend that she is getting a good deal? explain. the specific heat capacity of gold is 0.1291 j/g•°c.

She is not getting a good deal.

Explanation:

The equation that relates heat with mass, specific heat and temperature change of an object is .

Always convert temperature to Kelvin, although in our case it's not necessary because the will be the same, and we will leave the mass in grams because we will be getting units for specific heat, which we can compare to the one given for gold.

We then calculate the specific heat of the object in question:

Which shows it's not gold.
