Apiece of copper with a mass of 218 g has a heat capacity of 83.9 j/°c. what is the specific heat of copper?

The answer to this question would be: 0.385  j/g°c

Specific heat is the amount of energy needed to increase 1 degree of celcius per one gram of a specific mass. In this question, it needs 83.9 j/°c energy to increase the temperature of 218 g copper. Then, the specific heat would be:  (83.9 j/°c) / 218g= 0.38486  j/g°c

Elias is almost correct. he just got it backwards.the correct answer is that it demonstrates elastic potential energy transforming into kinetic energy.

It shows that the experiment is designed properly.
